To tell the truth, in China's book distribution industry, what matters is the relationship, and books are the second best. For the whole industry, there are fewer and fewer people studying at present, and the price of books is relatively higher and higher. If you want to meet more people and learn some communication, you can. If you want to survive in the book industry, I advise you not to enter it.
Remarks: If you enter the publishing house, it is better than private channels.
