Those taboos are only considered by people who think carefully. So when giving gifts, just don't give things that everyone knows the meaning of. Like pears and umbrellas, they both mean separation, so don't give such things. Friends certainly hope to be together forever.
Also, lighters cannot be given to each other. This should be well known. Lighters mean "I will not marry anyone but you". If you are just good friends, this is a taboo.
Also, scarves and bracelets should not be given to each other if you are not in a relationship or are not lovers. Wind chimes have a meaning of breaking up, but also a meaning of missing someone. Because you don't know which meaning your friends will care about, so try to avoid giving them.
If you are just ordinary friends, don't give underwear to each other. That is a sign of intimacy and a big taboo; pillows mean wanting to spend the night with you. These things with overly intimate meanings don't matter if he doesn't know, but if he knows, it will make you look very embarrassed.
Socks also have bad meanings, representing the desire to keep a certain distance from you. These are things that are widely used and have bad meanings. I don’t know if what I said is helpful to you, but if your friend doesn’t care about these, he will like any gift you give him.
