My classmate’s feet smell bad, and it’s hard to tell him.

Haha, I don’t know how to answer you. I want to know what will happen after you tell him that his feet are smelly? Do you mean you just want to tell him that his feet smell, or do you want to give him a tip? No matter what kind of person he is, it will be very embarrassing for someone to tell him that his feet are smelly and ask him to pay attention to it. I think he should also know about the smell of feet. I don’t know whether he likes slippers or wearing breathable shoes. I think There's nothing he can do about it... because after all, foot odor is not what he wants... People with foot odor can't resist washing their feet often. They may need some medicine or traditional Chinese medicine to soak them... If you and him The relationship is good, and you have found a solution. You can talk to him as a friend. For example, you talk about other things first, and then you can say that your feet are smelly and you want to solve it, just like with a friend. Complaining way, and then tell him what you have been using to soak your feet recently, but you must pay attention to the way you speak, haha, I think this is a solution, and then see if there is a doctor, or This is the answer from someone who has had similar experience but has solved it, haha.
