In addition, in addition to saving water, it was also easier to manage. If there was a flushing device in every position, not to mention the waste of water for the time being, there was also a problem with the operation. The children were very young, and they might not learn well. They would either not flush or break the flushing device. In short, there would be a lot of trouble. In order to avoid these troubles, the best way was to flush all the way to the end.
When there was someone using it, in order to prevent the toilet from smelling, it naturally needed to increase the frequency of flushing. However, when there was no one using it, if it kept flushing, it would seem a little inappropriate. This was a great waste of water. Therefore, the automatic device also had its limitations. This simple floating ball device could not be as intelligent as the human brain. This was just a non-intelligent device. Therefore, many times, it still needed to be manually controlled. For example, when class was over, someone would be responsible for opening the valve, and during class and school, the valve would be completely closed. In this way, the problem of insufficient intelligence could be solved.
However, if the person in charge of this carelessly forgets, it will lead to either a waste of water or a smelly toilet. However, fortunately, it is not a big deal, it is just a small matter. The position of this switch is not high, and the children who are a little taller can get it. At that time, they only need to give the task of boiling water and turning off the water to these children. Of course, not everyone can do it. Only some people will be on duty according to the date. It is easy for five people to be responsible for a toilet for a month. These children have very good memories. It is impossible for all five people to forget. There will always be someone who can remember. After school in the evening, many teachers on duty will check and make sure that there is no problem before leaving.
Of course, not all the teachers left at night. There were a few teachers who were foreigners. Before entering the Sound Transmission Academy, they stayed at their friends' houses. However, it was not a good idea to always stay at their friends' houses, especially when their friends' wives looked at them with such unfriendly eyes. Therefore, after entering the Sound Transmission Academy, they requested to stay in the academy, even if it was in the woodshed. They did not want to live under someone else's roof anymore. However, before the construction of the Sound Transmission Academy's teaching building was completed, Li Chuandao did not agree to these people. This was because the classrooms were still tight, and it was very unrealistic to arrange a dormitory for them. Although they asked for a woodshed, how could he really arrange a woodshed for them? This would destroy the image of the Sound Transmission Academy. It was a disgrace to let a teacher live in a woodshed. Scholars had to be dignified, and living in a woodshed was obviously impossible. Therefore, Li Chuandao naturally could not agree to them. After the construction of the new teaching building was completed, there were more empty rooms. Although some of them had been transformed into functional classrooms such as libraries and art studios, there were still many left. Therefore, these teachers who did not have a proper residence lived in the academy. They could also play the role of guarding the entrance, which was only beneficial to the Sound Transmission Academy. In any case, there were many empty rooms, and many of them were originally designed for people to live in, so there was no need to change them.
The toilet was not a good place. Yan Ruyu went to the female toilet to take a look and came out. She felt that it was not bad. It was clean inside, and there was no smell at all. Such an environment was quite satisfactory.
"My husband is really thoughtful. Even the toilet room is so good."
"Why not do it all at once and do the flushing as well?"
"That would be too wasteful of water. There are 1,500 students in the academy. If we install flushing facilities in every place, it would be too expensive. Moreover, this is not something that children can use well."
Everyone said.
The flushing water was not for flushing the toilet, but for flushing the buttocks. In Ang Lee's house, there was not only water for flushing feces, but also water for flushing the buttocks. Flushing the toilet could make the toilet room cleaner and fresher, without any unpleasant smell, and flushing the buttocks could avoid the trouble of using the toilet and not cleaning the toilet paper.
In later generations, when going to the toilet, most of them used soft paper, but in ancient times, they generally used toilet chips. Whether it was paper or toilet chips, in fact, it was difficult to completely wipe the buttocks clean. There would always be some residue that could not be wiped clean. Therefore, if one often did not change their underwear, there would be an unpleasant smell on the body. If they used water to wash the buttocks, it could basically eliminate the situation of not being wiped clean, and the buttocks would be much fresher.
Whether the buttocks could be wiped clean was not a trivial matter. Not to mention that the smell on the body would affect normal communication, and if it was not wiped clean, it was easy to cause bacterial infection, which would lead to diseases. Men were better, and the chances of getting sick were not high, but women were easy to get sick. Washing with water would not have such a problem, and it could be very good to avoid this risk.
In addition, because the toilet chips were too hard, it was easy to scratch the skin, causing the skin to produce a protective stratum corneum, and even directly grow a meat lump.
Naturally, it was very uncomfortable for the human body to have a lump or rough skin in that place. As long as they rubbed it with rough paper, it was very easy for the flesh to grow thorns. As long as they persisted in flushing their buttocks with water, the lumps would disappear in a few months. If they continued to use paper, the lumps would appear again very quickly. However, this was for the elderly. For the average child, it would not be so serious. Children were more mischievous and had better resistance, so they would not have the phenomenon of sitting for too long. Adults, on the other hand, were more prone to diseases. Growing thorns was considered a light matter. If it was serious, it would be fatal if they developed hemorrhoids. Therefore, Li An chose to install a full set of washing equipment at home. As for the school, it really did not have such facilities. Every day, the consumption of clean water for flushing the toilet was very large. These clean water had to be transported to the roof bit by bit. The greater the amount used, the higher the labor intensity of the transportation.
"Come, let's go to the roof and have a look."
After Ang Lee led everyone to the third floor, they continued to walk up. After opening a door, they entered the platform on the top floor.
The platform on the top floor actually had a guardrail, but this guardrail was not very high. If one was not careful, it was still possible to fall, so it was better not to go to the top floor for no reason.
But this top floor could actually be modified. As long as reliable protective guardrail and protective net were installed around it, it was completely possible for people to play on it.
At this moment, on the top floor platform, except for a few large water tanks in the toilet, the rest of the place was clean. There was nothing, and it looked a little desolate. However, if one stood on top and looked out, the scenery was still good.
"There seems to be something missing here?"
Yan Ruyu said.
"Madam, this is the top floor. No one usually comes up here. What should we put here?"
Ang Lee said.
"That's true, but if we put some flower pots on the edge, it can be seen from below. When it's blooming season, the fragrance will spread throughout the school. Isn't this good?"
Yan Ruyu said.
Ang Lee nodded and said, "Madam's words make sense, but if there is a strong wind, the flower pots may be blown to the ground. It will be terrible if they hit the children."
"Oh! Really, if we encounter such a situation, it will be terrible. Forget it, let's not put them. Safety is the most important. "
Yan Ruyu said.
Ang Lee said with a smile, "In fact, it doesn't matter. We just need to install a higher guardrail at the position of the cement guardrail, then we don't have to worry about the flower pots falling. At that time, there will be a few rows of flowers around the platform and in the middle. The effect will be very good. The school with the fragrance of flowers will be very beautiful."
Green roofs were actually quite normal. In later generations, many buildings were green roofs. The buildings looked better, and the environment and air were better. In ancient times, such buildings obviously did not exist, because ancient buildings were generally very short, especially the buildings in the East. They were all wooden structures, and their strength was not very high. It was very unrealistic to green roofs. Once there was too much green, it was likely to cause great damage to the building, and it was very likely that the building would collapse.
Moreover, in order to prevent rain, the roofs of buildings were generally not made into platforms. Most of the roofs were slanted. The more rain there was in the area, the more the roof was slanted. In such a slanted building, even standing was very difficult, let alone planting flowers and trees.
Only a solid building with a platform at the top could fulfill the requirements of planting flowers and trees. If the building was not solid and the roof was slanted, flowers and trees could not be planted. It could not even hold a flower pot.
The School of Sound Transmission was a universal education school that Ang Lee spent a lot of energy to build. Since he had already spent a lot of energy, naturally, he did not care to continue to carefully carve it. The more perfect the school was, the better Ang Lee's mood would be. Every detail of the school was very important, so it must be built perfectly.
After coming down from the teaching building, Ang Lee took everyone to the playground to watch the children play games. These children were very naughty, but under the teachers' training, they could only have planned activities. They could not play casually. They had to do whatever the teachers asked them to do. They could be lively and laugh, but they could not mess around. They must be within a controllable range. They absolutely could not fight. Otherwise, they would not be able to eat meat at noon.
The teachers used food as a weapon to train these naughty children into obedience. All the naughty children obediently obeyed the teachers' requests. No one dared to disobey. Otherwise, not only would they be beaten with a ruler, but they would also not be able to eat the delicious braised pork at noon, let alone the candy.
These children on the playground were lively and not chaotic. Every child was smiling, and their spirits were very high. No one messed around. This made Yan Ruyu and others who passed by very satisfied in their hearts. They did not expect that these wild children from poor families could be so obedient and sensible. This greatly exceeded their expectations. Usually, they could also see children from poor families. They were very naughty and wild. There were also many fights. It was really rare to see a school like the School of Sound Transmission.
What they did not know was that these children were trained. Each child was a trained monkey. The teachers in the school used a ruler and delicious food to train them. Those who performed well would be given a piece of candy, and those who did not perform well would be beaten with a ruler. In this way, how could they not be trained? This logic was the same as the zoo's training of small animals. Look at the zoo, the more wild animals were trained to be obedient, let alone the poor children who were far less wild than animals. As long as the rewards and punishments were appropriate, they could be trained to be obedient and let these children grow up according to the ideas set by the school.
Even if all the students in the school came to eat together, this cafeteria would still be able to accommodate them. It's still far from the time to eat, but the kitchen is already busy preparing. Selling vegetables, washing vegetables, washing rice, and cutting meat all require a lot of time. Although there are more than 20 people in the kitchen, they are very busy every day. In order to let the students and teachers eat in time, they come here early in the morning. Some of them even come here before dawn. "
As soon as Ang Lee finished speaking, a large cart of coal was transported into the school. These coal were naturally prepared for the kitchen. Because many people had to cook every day, the demand for fuel was very high. Therefore, such carts transporting coal would enter the school from time to time. Almost in a few days, they would bring a cart of coal to meet the normal needs of the school.
In many provinces and counties of the Tang Dynasty, the dye used by the people was generally firewood. However, in the capital of the Tang Dynasty, most of the people had started to burn coal. The energy value of this fuel was higher than that of firewood, and coal of the same weight was more durable than firewood. It was a necessary resource for living. The reason why coal was popular in the capital was not because the ordinary people in the capital were rich, but because there were too many people in the capital, and the supply of firewood around was very tight. Moreover, many places were gardens of the imperial court and private forest products of the rich and powerful. There were not many ownerless trees that could be cut down by woodcutters. With the expansion of the capital, the ownerless trees in the surrounding areas were almost cut down. If one wanted fresh firewood, they had to be transported from far away. For firewood, the transportation cost was very expensive. Once the transportation cost was added, the price of cheap firewood would increase several times. Therefore, it was easy to see that the price of firewood was almost the same as that of coal. Even if it was twice as cheap, the people preferred to buy coal. After all, the energy value of coal was much higher than that of firewood.
