Who am I? Hunt for heritage drives Chinese to DNA tests

A combination of factors—a lack of formal records or destruction during China’s wars and the Cultural Revolution—have meant there are few ways for Chinese to trace their genealogy in the ethnically diverse country.
But with a growing middle-class, an increasing number are now keen on tracing their roots, and DNA testing companies are cashing in.
China’s DNA sequencing market was worth about 7.2 billion yuan ($1.05 billion) last year and is forecast to grow to 18.3 billion yuan in 2022, according to estimates by Beijing-based CCID Consulting.
