The market is still moving around the shock at the daily level, and the daily level is repeated, a typical grinding market. The high in the early morning reached the 69,300 line, and the retreat did not break the 67,000 line support below. At present, the short-term has ushered in a reversal, and the previous pressure level has been converted into support. The lower support level is 67000 and the pressure level is 69000.
