So what should I send or not? I think it's best to read it, because at least you already know the content of this book and send it to someone. How much should you know about that man? I believe I know what people who receive books will probably like, so what I have read is more worthy of recommendation. In addition, after delivering the book, there will be at least some topics to chat with * * *. After all, the books are the same, but everyone's experience is different, so in this respect, sending a book that you have read can invisibly add some topics to both sides.
To say the least, if you haven't read a book yourself, but if the recipient of the gift might like it, you should at least know the general content of the book to be given, otherwise you will give it away without knowing what it is written. If it's not the other person's favorite book, it may be embarrassing. For example, he usually likes all kinds of novels about cultivating immortals, but you send a romance novel. Although it may be a best seller, it is estimated that it is unlikely that he can read it because of his different tastes.
And if you send some books you haven't read, you'd better ask him what he likes first. For example, he has always liked a book but hasn't bought it yet, and if you know about it, you might be happy to buy it for him. In this case, it doesn't matter whether he has seen it or not. After all, the gift to be given should be liked by the recipient.
Books are the essence of knowledge, don't give them to those who are more material, it's a waste!
