The woodworking union attaches great importance to this festival. Woodworkers used to pay great attention to the spirit of respecting teachers and valuing Taoism. The most respected teacher was Luban Shixian. Woodworking is the oldest industry, and it has always played an important role in the construction industry. Every year, there is a very special traditional activity, that is, to congratulate the master on his birthday, that is, to send "master rice" The so-called "old man's rice" is actually just white rice cooked in a big iron pot on his birthday, plus some fans, shrimp, plum beans and so on. According to legend, children who eat the rice handed down by their teachers can not only be as smart as Lu Ban, but also grow up quickly and healthily. In the past, it was a big event to invite a group of artists to come back to sing Bayin or puppet show on their birthdays, depending on the economic situation of that year.
