Go to Dahuang Village, Jindong District, Jinhua, and now the whole village is famous for making shortcakes. The brand is Huang Jia chun Lian ~ you can buy it and eat it. It is available in supermarkets. It seems that it can be taught systematically there ~
If you can't, go to any pastry shop in Jinhua, which means that you can usually come here ~ but you just need tuition ~
Hehe, I hope it can help you ~
