The majority of Ruan's fortune is derived from his stake in Flat Glass Group. The Jiaxing, Zhejiang-based business makes about one-fifth of all solar glass, according to its 2021 annual report.

Ruan owns 66% of the company's Shanghai-traded A shares directly and with his wife and daughter, according to the 2022 third-quarter report. Ruan is credited with all of the stake to reflect his status as co-founder and chairman. About 2% of his stake is pledged and removed from the calculation.

He also owns less than 1% of the company's Hong Kong-traded H shares, according to the same 2022 third-quarter report.

A spokesperson for the company didn't respond to a request for comment on the net worth calculation.
