Dezheng is a chain of hand-operated stores that has started to develop relatively recently, and its business methods are very different from the current mainstream. First of all, he only makes oolong original tea and oolong derivatives, so there are not many items to choose from. But also because of the single choice, the quality of his oolong tea is good. When combined with other drinks, such as sugar cane, lemon, coffee, etc., they can all taste good. This is why it has become so popular in recent years. .

Secondly, the aesthetics of the furnishings inside and outside the store are consistent, focusing on the modern and simple trend, and paired with their signature Dezheng blue. It makes consumers feel relaxed and at ease from the moment they enter the store. They don't need to face complicated menus or hesitate at the ordering counter about which drink they want. The menu is also simple, so the introduction of the items allows the customer to easily understand what his drink today may look like and taste. This is something that other beverage stores have not specially designed so far.
