After the initial development in office buildings of Luohu district, the Shenzhen company relocated to an innovation and technology park in Longgang, and now has about 200 employees with its own manufacturing chains.

Compared with the situation 11 years ago, when he started from scratch in the city across the border, the overall environment for Hong Kong young people to operate business in Shenzhen is much better, especially in terms of financial support from the Hong Kong government, said Pun.

He said that in March 2019, the Hong Kong government launched a program to offer a maximum seed fund to provide HK$600,000 (US$77,300) to each eligible startup team. This was unimaginable a decade ago, when Pun and his team had to rely only on themselves to seek investment, Pun said.

Pun encouraged youngsters sitting on the fence to embrace the improved environment and consider emerging areas such as biotechnology, AI and educational technology. That's how he got to where he is now.
