How to talk to leaders about studying abroad for leave within the system

1. Be sincere when asking for leave with the leader. If you don't ask for leave in person, you can call the leader for leave, or you can send a message for leave. Don't send a message on WeChat or QQ for leave, which seems to be ignored.

2. Pay attention to the words when asking for leave, and ask the leader for leave in a asking tone, asking the leader for approval, and saying that I will be very grateful to the other party.
