Hello Feishaomin,
I'm currently trying to answer all previously unanswered posts in this forum category.
I suspect that this issue is no longer active.
If it still is, then please let me know so that I can try to help you.
Kind Regards,

If someone helped you, let them know. Mark as solved and/or give a kudo. 😉
