Su Kune [7th cent.]:—The lei huan is the ling 
produced by the bamboo. The balls are not joined together. 
It is produced in Fang chou [in Hu pei, App. 35] and 
Kin chou [in Shen si, App. 143}. ; 
Li Sui-cuen :—The lei huan varies in size. It is like 
a chestnut and sometimes like the chu ling [see 352]. It is 
round, has a black skin, white flesh and is very hard and 
compact. The lei huan, like the 4 #= lei fu (thunder-axe) and 
the @ #& lez sie (thunder-pile), are productions of the thunder- 
clap, and metamorphoses of the subtile vapors of plants. It is 
produced in the ground and is without leaves. It has the 
power of destroying worms and driving out evil spirits. That 
produced on the bamboo is called #f 2$ chu ling.
