Ceng Shiqiang said it doesn't matter. Don't read the yearbook

I haven't bought the Book of Changes. I don't know if it's really a complete collection or something. As for the need for money, I think it is normal. After all, I have always been responsible for the explanation. The recording, publicity and distribution are all done by a team, and the team itself needs funds to operate (paying salaries, renting offices, traveling, etc.). ). So even if you ask Zeng Lao why he charges, Zeng Lao is helpless. Many people need to raise them. What if they don't charge? Even when Confucius teaches students, he has to hand in ten pieces of dried meat, so it will be more precious to spend some money on learning!
