(Huang Lvzhuang) There are so many systems that I can't remember them clearly. I still remember that it is a two-wheeled vehicle, three feet long, which can sit around one person and walk by itself without bothering to push or pull; When walking, the arm turns around the axis and returns to its original position; Take it with the living, and you can walk 80 miles a day. As a wooden dog, put it by the door and lie down as usual, but when people come into the house, they bark as soon as they touch the machine, and the barking sound is the same as the real one, although the deaf can't tell the truth from the false. As a wooden bird, put in a bamboo cage, it can dance and fly, sing like a thrush, and the more sad it is, the more audible it is. As a container for holding water, water is put in the container, and it shoots like a line from bottom to top, five or six feet high and constantly moving. What was done was so strange that it was impossible to record it.
Translation:
I can't record all the artifacts made by Huang Lvzhuang. I remember he made a car with wheels, which was more than three feet long. A person can sit down. He can walk with it, control it with his hands, go anywhere and walk 80 miles a day. Make a wooden dog and put it by the door, then you can enter the house and touch the mechanism. Dog barks are very similar and unique. Smart people can't hear it.
