Within about a month, I have seen it in the old books of Confucius on the Internet, and I have seen it in summer and autumn. The difference between the two prices (referring to the closing price) may be due to the different participants, preferences and economic strength of bidders.
Single volume (incomplete, see flower-and-bird volume, landscape volume) is also seen in the auction, and 200 yuan shoots around.
Today (1.4), a set of four volumes has just been completed, with envelopes, and the starting price is 2000 yuan, and it is auctioned. You can go and have a look.
