Where are the mushrooms of Mufeng, the former god, collected?

Mufeng mushroom is an important breakthrough material in Genshin Impact. Mona, Kelly and Barbara all need it. Mufeng mushrooms are only distributed in Mond: Mond City, Qingquan Town and Chenxi Winery. Most of Mufeng mushrooms grow under the eaves and a few grow on trees. Colleen's friends can put her in the team, because Colleen's talent will mark Mond's specialty in the small map, which can help us find her breakthrough materials. A florist named Caroline can buy five at a time, and she will get six when she talks to Michelle.
