Core highlights:
* Cultural memes: Concrete "Japanese origin theory" in the folk (such as the origin of surnames, splitting characters to create Chinese characters, Bushido is the way of the Wu family) into a plot.
* Cute contrast: Wu Dalang took advantage of his "three-inch" figure and was regarded as a "god man" in the island country; Pan Jinlian improved the custom industry model in Tokyo (Bianliang) and exported it overseas.
* Refreshing rhythm: Starting from selling cooking cakes in Qinghe County, going to sea to found the country, and finally making the island country the "loyal younger brother" of the Song Dynasty.
