It is rude to disrupt/intercept/interrupt when the meeting is still on.
啲同事開緊會, 唔好嘈住， can？
What do you want to ask? 唔好嘈 mean " stop making noise" 住 is a particle emphasize " for this moment"

do we say regular maintenance ( not Repair ) work as 維修？
The term 維修 is combination of "maintain and repair"
to be specific,
maintenance = 保養
repair = 修理
