It is difficult to travel to Hong Kong. What department should the mainland look for?

Hong Kong has the Liaison Office and the Ministry of Foreign Affairs, and China citizens can turn to them for anything in Hong Kong.

If it is a passport or certificate problem, please contact the Hong Kong Immigration Department or the China Foreign Ministry Office in Hong Kong.

If Hong Kong people bully you or beat you, you can call the Hong Kong police, but it is hard to say whether the Hong Kong police can stand on the side of mainlanders.

If you lose your wallet, you can explain the situation to the police on the way.

I wish you a pleasant journey and a safe journey.
