Shenzhen and Hong Kong are separated only by the narrow Shenzhen River. Hong Kong residents are used to calling their trip to Mainland China "crossing the river". People in Hong Kong are increasingly "crossing the river" to work, start businesses, reside and live in Qianhai, west of the Nanshan District in Shenzhen. They see Qianhai as the starting point and a milestone for achieving their goals. On the 25th anniversary of the handover of Hong Kong, our crew will focus on Hong Kong residents in Qianhai who "crossed the river" and established their businesses. This documentary series presents the new vitality of the Greater Bay Area and a new perspective on Hong Kong residents through their stories.
