The anchor asked in private how to reply to the address.

The anchor's private message requires a wide range of address replies, which is safe. The anchor refers to the "host announcer". Simply put, broadcasting is reading other people's words. The host is talking about himself. Anchor does more work than announcer, and it is a combination of announcer and host. The announcer only needs to broadcast and read the manuscript, while the anchor needs to do a series of work such as planning, editing, interviewing, producing, guiding and presiding.
