Liu Nan is the co-founder and CEO of Mia, a Chinese e-commerce site and app specializing in products for infants and their parents.
When Liu became a mother, she says she found it hard to know which products to trust.
She began researching products online and sharing the findings, turning her into an opinion leader among Chinese mothers.
Liu would go on to start Mia in 2014 as a shopping platform for quality baby goods. It has expanded to include all kinds of household products.
