Qi is composed of two chelates, so it is called chelation. Long Mai was tired, and the stars stopped, but there was always a hard place with no holes and dimples in the pliers. The air at the bottom melts, and the two tongs get together, forming holes in the middle with slight bubbles, such as tongs, also called the shape of double clam steamed bread.
