1. Cross Shenzhen Bay, take B2P to Tin Shui Wai, cross the overpass into the subway station, take "west rail line" to Nanchang, and change to "Tung Chung Line" to Tsing Yi. The estimated fare is 35 Hong Kong dollars.

The subway transfer in Hong Kong is very convenient, and it doesn't leave the station.

2. If you are traveling with five people, it is also cost-effective to take a taxi, because a taxi in Hong Kong can take five people except the driver. The fare from Shenzhen Bay Port to Tsing Yi is about HK$ 240, with HK$ 48 per person.
