To be honest, I haven't been to 4150, I've only been to 4153.

Moreover, the live broadcast mentioned that the closer you get to 4150, the more you can do a rebound.

Regarding the live broadcast about doing it to the left of 4300, as mentioned in the morning session, reduce by half a position, and still pay attention to whether 4150 can break down to determine if a small-level pullback and fluctuation begins.
