This question is too general. Because there are many ethnic minorities in Yunnan, there are also many ethnic autonomous regions, and different ethnic flavors and food snacks are different from place to place.

For example, Kunming's famous rice noodle crossing the bridge, Jiahua flower cake, cold noodles with shredded chicken, tofu pudding rice noodle and so on.

Dali: Bai nationality three teas, milk fans, river boiled live fish, raking meat bait, burning bait blocks, etc.

Lijiang: Lijiang Baba, butter tea, bean jelly, preserved ribs, glutinous rice sausage, etc.

Xishuangbanna: Dai people burn ganba, fresh bamboo shoots, ant eggs and Dai bamboo rice.

Dehong: Dai cuisine, tropical fruits, Dai bamboo rice, mangshi pickles, etc.

There are also local snacks in Baoshan, Zhaotong, Qujing, Wenshan, Yuxi, Pu 'er and Lincang.

Words are dull. I hope you can travel to Yunnan and taste it yourself, and you will know how many delicious foods there are in Yunnan. I hope you can adopt them.
