• Nobodies behind $7.7bn industry

A 21-year-old student walked around her campus in China using invaluable skills she learned in class: Holding a selfie stick aloft, she livestreamed her random thoughts and blew kisses at her phone.

Jiang Mengna is majoring in “modelling and etiquette” at Yiwu Industrial and Commercial College near Shanghai, aspiring to join the growing ranks of young Chinese cashing in on internet stardom. Hordes of Chinese millennials are speaking directly to the country's 700 million smartphone users, streaming their lives to lucrative effect, fronting brands and launching businesses.

They are known as “wanghong” — literally hot on the web — and they now represent an industry worth billions and so big it even has its own university curriculum.

At Yiwu Industrial and Commercial College, the classrooms for Jiang and the other 33 mostly female students are typically dance studios, catwalks strafed by flashing lights, and bustling makeup rooms. The skills taught include dressing fashionably, applying make-up, performing on camera, and knowing various luxury brands.

“I like dressing myself up really pretty and take pictures. I feel like this major really suits me,” Jiang said. She spent 30 minutes at lunch musing about her day to her internet audience.

She was rewarded with a quick 60 yuan in “virtual gifts” — emoticons with small digital values that comprise the main income for many aspiring wanghong, at least until they go viral.

“The requests and demands for our major are rising because the e-commerce industry is developing rapidly,” said Hou Xiaonan, a dance teacher. Wang Xin, 20, switched from accounting to a major in wanghong.

“I have always had an idea, a dream to be on stage with the lights on me and the crowd watching me,” Wang said.

Nobodies behind $7.7bn industry

The students are trying to follow in the footsteps of people like Wang Houhou, a self-described shopaholic, and her friend Wang Ruhan. When they began posting tips on China's social media about good fashion and where to find it last year, the pair had no idea that their new hobby would make them money.

But soon enough, the Shanghai-based duo's posts and videos won hundreds of thousands of viewers, and retailers followed, vying for their endorsements. Like other wanghong, they are now leveraging their cyber-fame with an e-commerce fashion business which they launched earlier this month.

“I would just find a very interesting item that I would wear, and I would take weird photos of it and post it on the blog, and people really go and buy this stuff,” Wang Houhou said, almost in disbelief.

Internet consultancy Analysis International estimated China's wanghong industry was worth $7.7 billion last year and would double by 2018.

“A nobody can suddenly become prominent and average people can become celebrities,” said Yuan Guobao, author of “The Wanghong Economy.”

—A wanghong is born

The patron saint of wanghong is Shanghai's Jiang Yilei, 30, a graduate of a top China drama academy whose low-budget comedic video rants on everything from urban life to relationships went viral last year.

“Papi Jiang”, as she is known, now has 23mn followers and product endorsements including New Balance footwear and luxury watchmaker Jaeger-LeCoultre. Wanghong content is typically bland day-in-the-life livestreaming that earns small digital monetary gifts from fans.

But many wanghong are profoundly impacting China's bustling e-commerce as retail “influencers”, said Zhang Yi, head of mobile-internet consultancy iiMedia Research Group.

The phenomenon provides businesses with a powerful new, highly visual, promotional alternative and is eating into the business of Chinese internet goliath Baidu, which dominates online advertising. “Now someone will wear (the product), try it, use it, and persuade you to buy it,” said Zhang, who estimates wanghong now influence up to 20 per cent of online purchases.

“It's a booming business. Wanghong have their own followers who can easily be made consumers of the brands they recommend.” New incubator companies, formed to find and groom wanghong, are cashing in, such as Ruhan Holdings, which last year drew 300 million yuan in investment from e-commerce leader Alibaba.

Wang Houhou returned from studying English literature at a US university last year to discover that attractive fashions she saw overseas were hard to find at home. Young Chinese women lapped up her playful posts about navigating Taobao, China's Amazon, and other e-commerce platforms, and clothing brands began paying her and Wang Ruhan to showcase their items.

“If we hadn't started the blog, I would probably be in investment or finance,” said Wang Ruhan, 24, who never expected to be an entrepreneur so early in her life.

“We have to do this without much experience and just figure out the right way to do it.” She spoke as they prepared for the launch in Wang Ruhan's Shanghai apartment, with Ruhan dressing amateur models in various outfits and Houhou snapping pictures as music played and mist from a clothes steamer filled the air.
