The whole family travels through time and space, and the three of them struggle together

Near the Lunar New Year, a shop called Datong Bathroom Decoration Workshop opened on Beijing's busiest street. It was a peculiar place, displaying only a few oddly shaped chairs? A large vat? Two things no one could name. Furthermore, the staff even banged a gong to announce that anyone who placed an order would receive a kitchen set. Only twenty sets were available, and it was first-come, first-served.

Some curious people wanted to go into the store to take a look at what these two things were and why they were so mysterious.

As a result, once he entered the store, he wouldn't come out. The other onlookers looked at him and wondered, "What's going on? Why isn't he coming out? Could it be something really good?" No! He had to go in and take a look. What if he missed out on something good?

Then, people started to come into the store. As soon as they entered, the staff would stop what they were doing and greet them in unison: "Welcome!"

Then, a waiter will come over immediately and say, "Sir, please come in. We have a special test room here for you to experience it.

The person who came in to check it out originally wanted to come in and take a look. He didn't even know what was being sold here, so how could he possibly want to buy anything? However, since there was something lively going on, he might as well take a look. He was free anyway, otherwise he wouldn't have come here.

The clerk led the man to the test room and said, "We sell and install convenient flush toilets and bathtubs here. I don't need to tell you how convenient they are. Just try them and you'll see."

Then, the boy pointed to a porcelain object that looked like a chair and said, "This is a flush toilet. Open the lid and sit on it like a chair. When you're done, close the lid and flip the switch next to the water tank above, and the water will flush."

The onlooker did as the waiter said and opened the lid to take a look. Wow! The toilet was really clean! Then he flipped the switch again, and just as the waiter said, the water flushed down.

So the man asked, "What are you going to do if the water in your tank is gone?"

The young man had obviously answered this question many times. He pointed to the water pipe on the water tank and said, "See? There's a switch here. Once you turn it on, water will flow into the tank." Then he pointed to the lid on the tank and said, "This lid can be opened. There's a line inside. When the water reaches that line, you can close it."

The man tried it as the boy said, and hey! It was true. The man was curious, "Then where does the water in your upper pipe come from?"

This time the boy did not answer him directly, but just asked him to be patient and he would show it to him later.

Then the waiter started to introduce him to the bathtub. The man looked at it nonchalantly and said, "Isn't this just a large bathtub? Yes, it's made of white porcelain instead of wood, but it's still the same thing. What's so special about it?"

The young man was obviously good-tempered and did not argue with the other party. He just asked the other party to watch his next operation. He walked to the end of the curved pipe above the bathtub. There were two curved water outlets there, and there were switches on the two curved pipes. He turned on the switch painted red. After turning it on, water flowed in, and this time it was hot water.

The onlookers were obviously stunned by this scene. It can actually release hot water? It's amazing! So, he went forward to try it, closed it, opened it, and hey, it was hot water!

Then the boy explained, "We call this water outlet a faucet. Just turn on the switch and water will flow out. But the water in the two faucets is different. Turn on the blue-painted switch next to it." The man did as the boy said and turned on the blue-painted switch again. This time water also flowed out, but this time it was cold water.

"Hey, that's amazing! How on earth did you do that?"

This time the young man did not keep him in suspense and led him outside the experimental house. He saw two water tanks on the platform against the wall outside, and there was a water pump above each water tank. He recognized it because his family had also ordered one from Datong Trading Company.

The boy pointed to the water tank and explained, "These two water tanks, one contains hot water and the other contains cold water. Both are pumped in with a water pump. The cold water tank is directly connected to the well, and the hot water tank has a water pump pipe connected to the kitchen. If your home has a dedicated water boiler, you can also connect it to the water boiler. Leave a section of the hose outside and bury the rest underground or against the wall, depending on your home's situation.

When you need hot water, just put the water pipe into the water after it is boiled, and you can pump water here. After pumping the water, you can also cover it to ensure that the water cools slowly.

The man interrupted, "There's no need to talk about cold water. I have a water pump at home, too. I understand this."

Seeing he understood, the clerk didn't hesitate and showed the man the platform beneath the two water tanks. "If you want to install these two things at home, this platform is essential. As the saying goes, 'Water flows to low places, people go to high places,' and the saying 'water flows to low places' applies here. Whether it's a flush toilet or a bathtub, the water used is all from these water tanks. The water tanks are high, and the toilet and bathtub inside are low, so the water naturally flows downwards."

However, the platform shouldn't be too high, or it'll be difficult to pump water. The current height is fine; the water tank and platform together are about five feet high. If you're worried about running out of water, or if pumping water from the main pump is inconvenient, you can make the tank wider.

People watching the fun said, "I understand the water coming in, but where does the water going out go?"

The young man slapped his head and said, "Look at my memory. I always think that water is coming in. You have to follow me into the test room and I will explain to you how to get rid of water."

So the man went into the test room with the waiter again. The waiter came to the bathtub, pointed at the water inside and said, "After taking a bath, you don't need to lift the water out. There is a plug underneath." As he said that, he pulled out the black plug at the bottom of the bathtub. As he moved, the water flowed out.

The man looked around the tub and saw no water coming out, so he asked, "Where did the water go?"

The young man smiled and said, "If you're going to use this water at home, you can designate a place to store it, and we'll install the pipes there so the water can be reused. If you don't need it at home, you can also do what we did and divert the water directly to the drainage culvert, so it can flow away."

The onlookers were suddenly enlightened. They realized that this was actually possible! So they asked, "Does the water in the toilet also drain into the sewer?"

The boy said, "That's not the case. The sewage smells too strong and cannot affect the surrounding environment, so it is discharged directly into the sewer."

"Great! Great! It's really great!" The people who followed in to watch the fun also exclaimed. They didn't stop there, "I want this bathroom installed in every room in my house. How much does it cost? I'm ordering it now!"
