What's Grandpa?

The so-called grandfathers belong to the research category of folklore, and are generally called the founders of academic schools, religious factions and all walks of life, or people who have made great contributions to the formation of an industry. Representative figures include Du Kang and Lu Ban.

Ancestor worship in the industry is a branch of folk culture. In the past, all industries attached great importance to it and regarded it as the patron saint of the industry. Moreover, there is a saying among the people called "360 lines, no ancestors."

Grandfathers are very prestigious people, who directly or indirectly created and supported this industry. Some people became ancestors by accident, others were forcibly installed by later generations, and some industries used a founder, such as pawnshop, fortune telling, candle industry, sericulture industry, silk weaving industry and pastry industry, all of which took Guan Yu as their founder.
