The upfront cost is about 20,000, including technology. But you don't have to join brothers and sisters. There are many unknown small shops in Zhengzhou, and Dongdong is also delicious. The technology is not bad, but the popularity is not that high. If you have a choice, the technical taste is similar, 2000 yuan a 20 thousand yuan. Which one would you choose? My friend had the same problem as you before, and then went to Zhengzhou for a field trip. Finally, he chose a small shop with a remote location but good business. The technical fee is 2000 yuan, including the machine. After returning to his hometown, he opened a shop and the response was not bad. The best way is to choose by yourself.
