You are talking about 1976, the Hong Kong film legend of bruce lee directed by Wu Siyuan and starring He Zongdao. The film was shot in Hongkong, China, San Francisco, Seattle, Los Angeles, Bangkok, Thailand and Rome. Ye Zhun, the eldest son of Bruce Lee's master IP Man, was invited to play IP Man, and Chen, Bruce Lee's close friend unicorn, was invited to play himself. This film had a very wide influence in Chinese mainland, which led to a large number of Bruce Lee fans in the middle and late 1980s.

In the film, Bruce Lee exercises by electric shock. However, it is exaggerated. The machine is too big and scary. In fact, Bruce Lee's electric fitness equipment is very small. Many people have seen it with their own eyes It is only the size of a mahjong box, and it is only an electronic instrument. Wearing it can "exercise" his muscles.

The so-called "electronic instrument" is actually a pulse electrotherapy instrument, which is used to massage the body, muscles and abdomen. It is rumored that this is the so-called "electric shock muscle vibrator"
