Which famous brands of drinking cups in China should not be too high-end?

I don't know whether you want a stainless steel cup or a glass. Let me give you a general idea.

High-end brands of cups: Sinoe, Vientiane, Shuishen and Jinkou. These brands mainly make stainless steel thermos cups with higher prices.

Mid-range brand cup: Jiahui Fu Guang Yatai

Among them, Jiahui specializes in glasses. There are many kinds of glasses made in Fu Guang and Asia Pacific. If you are making glasses, I suggest choosing Jiahui or Yatai. I'll send you a picture of Jiahui glasses, but the others haven't been found yet.
