The reason is also very simple. Shopping malls are shopping complexes with their own traffic, and advertising fees alone will save you a lot. The most important factor for the survival of Xuecha milk tea shop is flow. Of course, you have to consider a competition issue. There are already several tea shops in the shopping mall, so naturally you don't touch this frown.
Regarding the brand, I just want to say, only choose the right one, not the expensive one. Keep your eyes open when choosing a brand. It's always right to look at several companies. Don't be afraid of hard work. You must visit their headquarters in person.
Wish you success!
