Management doesn't care about shareholders. There are two cases:
a) They are focused on building their business, and went public only to have liquidity in the future. The value of the stock is irrelevant to them; they want to expand their infrastructure and have plenty of funds available to do so. Thus they have no reason to rush out PRs.
b) They are a scam/fraud. In this case there are two sub-possibilities:
(b1) Insiders already sold into the ticker change euphoria. In this case they don't care about the stock at all. If anything, they want it to go down so they can re-buy and scam investors more.
(b2) Insiders have yet to sell, and will try to pump the price higher with PRs. In this case they might rush out PRs to hype up the stock.
So the only case where management would be rushing to put out PRs is if they are a scam. If you believe in the company, give them time. Chinese companies tend to be very formal with these things and do everything according to protocol. (That doesn't mean there isn't also a lot of corruption; there is!)
I am long, but trying to present a neutral point of view.
