2/kloc-can I book a hotel in hong kong under 0?

As long as you can apply for the Hong Kong and Macao Pass at your place of residence, you can book your own hotel online ... because you can't use the mainland ID card in Hong Kong ... you can only use the Hong Kong and Macao Pass ... so as long as you can apply for the Hong Kong and Macao Pass, you can stay in any hotel you want in Hong Kong ... provided that the reservation on the other hotel website supports ... payment and transit transfer ... but it is usually more appropriate to pay when you check in at the hotel front desk. ...

Two:

There are two checkpoints in Shenzhen that can go directly to Hong Kong ... 1 is Luohu Port ... 2 is Huanggang Port ... I suggest you start from Luohu ... and exchange Hong Kong dollars at a foreign currency exchange point nearby (it is recommended to exchange less ... because the exchange rate in the Mainland is higher than that in Hong Kong, And you have to pay taxes ... it's more cost-effective to change money at any exchange point in Hong Kong ... more than any exchange point in mainland China) ... and then you have to prepare for customs (pay attention to the X-ray machine of large luggage ... you can't carry dangerous goods ...) ... you can go directly to the train station bound for Hong Kong at Luohu Pass ... and buy a train ticket before entering the station (at this time, you need to use HK$ ... about HK$ 32.5 ... It is suggested to apply for an Octopus card at the ticket purchase window ... so that you can use ... eat ... take a boat ... take a bus ... even in the supermarket ... the deposit is 50 yuan ... When you come back from the customs, the 50 yuan will be refunded to you.

I wish you a pleasant trip in Hong Kong:)
