Please help me see 600246 Vantone Real Estate, what's going on?

When the word DR appears in front of the stock name, it means that the day is the ex-dividend and ex-rights day of the stock. On the ex-dividend day, the base price of the stock is lower than the closing price of the previous trading day, because the difference in interest is deducted from it. On the ex-rights day, the share price is also lower than the closing price of the previous trading day, because the share price is amortized due to the expansion of the number of shares.
