A ninja-themed movie

Pray for Death (1985)

Probably this one. I can't even find the Chinese plot, so don't even think about videos.

English plot summary:

A Tokyo businessman immigrated to the United States with his Japanese-American wife and two sons and opened a restaurant in Houston. What he didn’t know was that he was embezzling stolen goods. The police who violated the law used the storeroom of the restaurant to hide stolen goods. The gang boss wanted a necklace among the stolen goods, but a policeman took possession of the necklace, so the gang pursued it from the Japanese. They first kidnapped a son, and then drove and hit his wife and another man. A son, the Japanese couldn't bear it anymore and decided to seek justice on their own...

The video is on a foreign website and seems to be unavailable in China. I took a screenshot for you to see if you have any impression.
