the practical value of journalist-type hosts

who combine the dual functions of journalists and hosts

is becoming increasingly apparent.This study analyzes the mechanism by which journalist-type hosts contribute to "in-depth communication" through theoretical interpretation

path exploration

and case evidence.Research has found that practice promotes in-depth communication through four channels: assisting in the selection of precise topics

enriching narrative expression

improving professional judgment

and strengthening communication influence.The cases of outstanding journalist-hosts such as Zou Yun and Wang Zhi demonstrate the crucial role of practice in uncovering the value of issues

enhancing the impact of reporting

improving professionalism

and guiding social awareness.Currently

journalist-type hosts face challenges such as high work pressure
