Because I'm from Jiangxi, saying "Zi Qiao" in the dialect is just like saying "three sounds of plum", and this kind of thing here refers to a wild vegetable, which can be used as an ingredient in meat dishes. It tastes a little sweet and very delicious (of course, this varies from person to person, I think so). It can be picked in the mountains, just like "Artemisia argyi" (a plant that can be used as a green ball). Picking also requires a lot of patience, but the process is very enjoyable. I hope I can help you.
