Wenjindu Border Crossing
Wenjindun Border Crossing is a private car crossing only, connecting Shenzhen with Hong Kong between Luohu and New Territories.
When you arrive, you will stop at the Shenzhen China Gate House, exit the car and enter the building. After the immigration process is completed you can drive across the border. When you arrive at Hong Kong Immigration, you are not required to exit the car. Just pass your documents to the officer and he will do what is necessary. Then you will drive into Hong Kong.
Both immigrations require you to complete a form, sometimes 2, which are available at the desk where you can fill the form in.
