It is difficult to solve this problem in a short time. Even if 000002 has technical support near the 250-day moving average (commonly known as the annual line), it can only temporarily stop the decline. If you stop falling, you generally need to make a directional choice after a period of sideways. I suggest we wait and see what happens next. If you go down, it is recommended to reduce your holdings (if you effectively fall below the annual line, there will be panic killing). If it continues to exist.
