What is the connection between "Yonghe Soymilk" and "Traditional Yonghe Soymilk"?

Yonghe is the name of a place in Taiwan, which you could interpret as a town on the outskirts of Taipei.

Rumor has it that around 1950, a few veterans of the Nationalist Army from the mainland sold soymilk there, and that's where it came from.

What is certain is that the Yonghe Soymilk in Taiwan is certainly not an international chain.

As for the various kinds of Yonghe Soymilk in mainland China, it is a project used by a few Taiwanese who will do franchise business to attract business, that's all.

This franchise program used to attract business, today can be Yonghe Soymilk, tomorrow can be California Ramen, the day after tomorrow can be Rome Pizza, as long as you can earn the franchise fee on the line.
