It’s actually great news 
Here is the situation: a number of Gitea users and developers are native Chinese speakers, including @lunny, one of the owners. There even is a Chinese support section in the forum, a Chinese chat channel and a Gitee mirror of Gitea (I know… confusing 
). These are the primary reasons why it seems sensible to have a Chinese interpreter during the meeting.
However… this is the first meeting where such a possibility is offered and it is difficult to convince people to attend and try to ask questions in Chinese so that they are translated in English. It is unusual to say the least and I suspect it will take time before it becomes convenient. Ideally people will get use to it but we’re not there yet.
If you (or a fellow developer who speaks Chinese) are willing prepare one or two questions in Chinese, that would be very helpful. It can be very short questions, one or two sentences, right after the introduction talk for instance. If noone else ask a question in Chinese, there would at least be a recording of the simultaneous translation of those questions to show how it works at a later time.
Does that make sense?
