What brand of milk tea has a comma above and a comma below?

The first comma milk tea: comma tea. Address: Building/KLOC-0, Qingyue City, No.77 Xishi Street, Zhuji City (KFC is next to the toy store). The shop is small, black and white is simple, and the logo is a black comma that people can remember at a glance; There are mirrors on both sides of the store, and I feel that the design in the store is great and ingenious. This comma milk tea shop is also in Ningbo, the first in Zhuji. The photos in the shop are very beautiful, so you can take a selfie with a mirror. There are some cups, shoes, mobile phone cases and umbrellas with logo on the counter. They are beautiful and clean. It's a bit like Shanghai style, but this one is not expensive, relatively cheap and easy to shoot. They say it tastes more like a modern China tea shop. All the names with commas on the menu are symbols, and the names are meaningful and related to science.
