You are right and I believe he will never make this kind of mistake again. Thanks again for your replies 😄

Hello @@chengnay, I'm @12345678912345678912345678's friend. For some reason he could not reply so I'm here to do it for him. His reply is as follows: It turns out that the reason why it didn't work is that the system needs some time to switch the operation mode from the controller to hand signs after I put down the controller, and I was too early to start testing with my hands. I just need to wait longer and it works very well. There's no problem anymore. Thanks for the supportive and helpful instructions! I really appreciate it!
