Wuxi, you can go to nanzenji, there should be, but I heard that nanzenji's second-hand books are more expensive, I don't know the details, except nanzenji, there are also other places, usually second-hand book stalls, you can find them, there are many places.

Another way is to go to a waste recycling station or collect second-hand goods for recycling. There must be one.

If it is online, you can look at Confucius' old book network. There are many old books on this website, which are also cheap and good. Taobao also has it, but it is not as specific as Confucius' old book network. You can refer to them.
