If the competition is large in scale and involves large-scale online or offline events, then Tencent's authorization is needed in theory. Because such large-scale activities are often highly concerned by Tencent, Tencent will also provide corresponding official resources support.
If the competition is a small-scale community activity, you don't need Tencent's authorization, just explain the situation to the official customer service and pay some patent fees.
The above information is for reference only. If necessary, please consult Tencent staff.
