What gifts can't be given away casually?

What gifts can't be given away casually? Let me give you an example here. First, the clock can't be sent, because the clock represents the end, and the homophonic meaning is not good, so it can't be sent; Second, you can't send fruits to pears, because sending pears to others means separation and has a bad meaning. And a comb that won't work. If a man gives a lady a comb, it means that she wants to live with her forever, so she can't give it easily. There is also a wallet that can't be sent. If you give a wallet, it means that you have given your wealth to others. And you can't send colored hats, especially green hats. If you give them to men, you will attract others' fists and feet, and you know why. Also, girls can't give boys belts easily. If she wants to give a belt, it means that she has bound his life, so she can't give it easily. There are also personal clothes, you can't just give them away, because they are personal things, so there must be a difference if you want to give them, otherwise you will get into trouble. You can't send scissors, because sending them means that you make a clean break with her, which is not meaningful and can't be sent. You can't send alcohol and tobacco, because alcohol and tobacco are harmful to your health. You can't send an umbrella either, because the homophonic umbrella is scattered, which means it's not good and you can't send it. The rest needs to be observed by yourself. I think as long as you do it with your heart and avoid these taboo pits, I'm sure you will find the gift that you want to give and is suitable for that person.
