"Early to get to Wuhan" doesn't make sense here, since you haven't introduced the role of Wuhan yet in the writing. It seems like something is missing

"And" must connect related phrases. You could also write "and says that" or something similar, but if not, this sounds disjointed. "Goes on" is related to continuity (e.g. "the adventure goes on"). To say how something is, just use "go."

You've introduced a subordinate clause with "since" that does not fit anywhere and creates a run-on. You need to either separate the sentences or reword it, like "My father suggested my cousin remain in Wuhan because there will be great development potential … since Wuhan has all the attention."
