Luo is from Beijing. Luo's profile is "former TOMFORD makeup artist", and his work experience is mentioned more than once in the video, such as "TOMFORDBeauty20 17 National Sales Champion". Luo positioned himself as a blogger of weeding popular science, dispelling some rumors of beautiful women and IQ tax products, and teaching everyone to avoid digging holes and identify fakes. Not only is it well founded, but it is also very interesting. It's really telling you not to buy with your wallet: "We can be poor, but we can't be stupid".
