Oh, the Hong Kong and China border. How I love thee! Are you crossing the border? I have crossed the Hong Kong border up to four times per week at certain times.
There are people whose lives are spent crossing back and forth between Hong Kong, Shenzhen, and even Guangzhou. Even children, going to school each day, cross early in the morning, normally about 7:30 am to 8:30 am – you will see massive lines of children lining up with teachers or school assistants to help them get into Hong Kong to go to school. I don’t believe there are any students going the other way (Hong Kong into Shenzhen), so this tells you which side has the better education system.
