There are two separate scenes in this video.
A Kung Fu man from the North has come to challenge the Kung Fu schools in Foshan and is victorious. After defeating two schools, he goes to the next school, but the Sifu there is absent.
In the second scene, we find out that the absented Sifu is Sifu Liu and he is engages a fight with the Northerner and is defeated. The Northerner is very disappointed and seeks to find a better fighter.

Bandits arrive at the cotton factory for the second time and demands money. Unlike last time, the factory workers are prepared to fight back. Ip Man then comes to save the day.

Sifu Liu goes to Ip Man’s house while Ip and his family is dining. Ip invites Liu to dine with them. After a little bit of tea and dim sum, they spar; Ip dominates Liu; Ip says “jong”, signifying a hit, every time he lands a strike instead of actually laying the hits onto Sifu Liu.

The Japanese General is giving out white rice to any Chinese person who defeats the Japanese fighters at a ratio of 1 bag per 1 defeated fighter.

The General kills Ip Man’s friend in a 1(General)vs 3(Chinese men) duel. Right before the scene shown in this video, Ip Man witnesses Sifu Liu getting shot to death by the Colonel for losing a duel with 3 Japanese fighters and still dare to pick up the bag of rice he won earlier, though not by the orders of the General. Ip Man gets real pissed off, so he demands a fight with 10 of the black belts. Upon his victory, he refuses to take his reward(10 bags of rice) and the General tells him to “come back again”; Ip Man replies “I did not come here for the rice”. The interpreter tells the General that he will come back again. The General asks for his name and Ip Man replies “I am just a Chinese”. The interpreter tells the General, “He is Ip Man”.
