Starting from Tianshuiwei, I transferred to Lok Ma Chau Station twice, and then crossed the border from Futian Port to Shenzhen. At the junction of Lok Ma Chau Metro Station and Futian Port, there is a Kalemie. When she buys something and pats Octopus, she enters Futian Port. Then she goes to press a button to inform the staff, and she can return Octopus. The photo shows the passageway of Futian Port, crossing the Shenzhen River and heading for Shenzhen.
