你好。你的句子有问题。应该是All the people that / who attended the trade meeting yesterday have gone to HK ON a visit (today).”难怪你纠结。

All the people attending the meeting 中的attending是-ing形式做后置定语，修饰people，译成参加会议的人们，人们和参加是主动关系。相当于一个主动语态的定语从句All the people who attended the meeting about trade yesterday have gone to HK for a visit.
