The Lo Wu checkpoint, the first land port of entry between Hong Kong and the Chinese mainland, came into service in 1950. Many historic moments were recorded there, amid the changes taking place over several decades. During that time, China grew from a poverty-stricken nation to become the second largest economy in the world. Lo Wu also underwent remarkable changes, as infrastructure adapted to changing times and the software of a new era. The people who pass through the checkpoint every day, have changed, as well. Julianna Wu reports.
