The Boxer from Shantung (1972)

Ma Yongjeon needs to move to Shanghai, because he has repeatedly been in search of savings, and wanted to earn a very large fortune. He will be able to do this by moving to the designated area. He tries to be quite agile and accommodating in search of cooperation with local mafiosi. And suddenly he gets a chance to meet a criminal authority. It turns out that he can appreciate the skills of the guy's fighting culture, and offers him joint cooperation.

The hero did not suspect at all that he would have to fight with a competitive gang in the future. They seize the territory of the street and the areas of the local settlement, and try to keep them in their own control. They had never encountered such a force before, which the guy has. And they were very disappointed, because now they have to have the courage and spirit to resist him. An excellent fighter, without needing to advertise his skills, continues to fight for reputation in the group, and these mafiosi like it.
