An online sensation

A trendy, attractive young mother decked out in a bright pink velor Juicy Couture hoodie and matching pants, Yang has already published two books offering advice about relationships. The books have been so successful that she has recently bought a BMW car, "the favorite among the nouveau riche in China," she joked.

As an online sensation, Yang now has more than 620,000 followers on the Sina Weibo micro blog, China's equivalent of Twitter, and she likes to post photos of herself, usually ones in which she is scantily clad. Many of her followers consult her about relationships and makeup.

Her personal motto, "Those who are more beautiful than me are not as smart as me, and vice-versa" has become popular with many of her online followers.

She dismissed criticism that she lacks modesty with: "I am just telling the truth".

Fully aware of her beautiful appearance, she said she would be willing to sacrifice brains for more beauty.

"I have been super-busy running the shop, and I will resign as chair of Mensa China when my term ends," she said, explaining that her work for the society requires a huge amount of time and effort.

Her decision to join Mensa was purely pragmatic: To find a group where she felt she belonged, and more important, to land an intelligent boyfriend.

She achieved that goal, having met and married one of the members. The couple now have a 3-year-old son.

"He was among the smartest in the club and is definitely cleverer than me," said Yang of her husband, speaking with evident pride.

According to her latest book Treat Men as Animals, a stable relationship in Yang's opinion usually involves an intellectually superior man.

"I used to date someone with an average IQ, but the relationship only lasted one year," she said. "He couldn't understand my jokes and felt inferior," she added.

But it's different with her husband. "We can talk for hours, and he knows how to make me laugh," she said. Her husband, an accountancy graduate, helps her run their highly profitable online store.

"It's one of the biggest among those based in Beijing and we have hired eight people to help out," said Yang.

Currently, she's busy with her next book, also about relationships and cosmetics. "I seldom make plans and mostly do things for fun and the challenge," she said.

Mensa doesn't release details of its entrance test results, but a previous IQ test suggested that Yang's is around 145. That makes her sound like something between Stephen Hawking and Albert Einstein, but a high IQ is no guarantee of plain common sense; Yang has little sense of direction and the contents of her new handbag are a disorganized mess.

When asked if she feels she's wasting her brainpower by running an online shop, rather than working in science or a related field, Yang retorted that the question was as absurd as asking why tall people don't all end up on basketball courts. "I didn't choose to be super-smart, but I have chosen to take total control of my life," she said.
