What does Tangshan mean in Bruce Lee's movie "Tangshan Big Brother"?

From the film title and plot analysis, Tangshan in "Tangshan Mobile" is a plot in which all workers come from Tangshan, including the role played by Bruce Lee. Judging from the experience of filmmakers in the past, it is because many actors and extras in Hong Kong came from Tangshan and Shandong. In order to commemorate this point, there is also this meaning, but this meaning is very meager. 1993 In the New Year movie "Going East and Going West", Hong Qigong said the same thing about Shandong dialect.

Tangshan Mobile is based on a true story. Brother Tangshan, whose real name is Zheng Chaoan, lived in early Thailand. He came from Tangshan (another name for China by overseas Chinese) and made great achievements in resisting local bullies and oppressing overseas Chinese. Overseas Chinese in Thailand call him Tangshan Big Brother. A flower in Bangkok, Thailand, has a bronze statue of him, which was donated by overseas Chinese in Thailand to commemorate him. It has a history of more than 90 years.
