I am in Hong Kong. How to charge the mobile phone? The sockets there are different from those in the mainland. What should I do? Does the hotel have a converter?

Hong Kong uses an inch plug with three square holes. In fact, ordinary plugs in mainland China are not very good.

So you need to buy a conversion plug.

For example, the roadside supermarkets sell them, but the price may be around 15 yuan, which is not cheap.

If it is a hotel, just ask the front desk. 60% hotels provide adapter plugs, and there is no charge.

But if you really don't have one, go out and buy one. It's no use going home. You can keep it as a souvenir. Hehe ~ ~
