Dreaming of yam, as the name implies, is a medicinal material, dreaming of cucumber. According to our northerners' explanation, what will be spoiled means yellow, and it is a connected whole. You sell yam, which means to share the worries for others (medicine cures the disease, and the disease is trouble), but you also give cucumbers to others, which means that this matter will be ruined again. The overall explanation can be that you share the worries for this person, enlighten him, and then if you don't want to complain in the future, it's best not to persuade others to give up anything, just make it clear that the decision is up to him. I wonder if my answer can help you.
