For years, Hugo Barra was one of the most visible executives at Google. He was a product manager for its Android team. Every year at Google's biggest conference, Google I/O, Barra would show off Android's latest new features for the whole world. Then, in August of this year, Barra quit Google to work for a Chinese company. In December, he gave a talk in Paris about how utterly blown away he's been by that place.

This is Hugo Barra.

Barra used to be a top executive in Google's Android division.

In August he quit to go work for the "Steve Jobs of China," Xiaomi CEO Lei Jun.

After just two months in China, Barra spoke at the Le Web tech conference in Paris in December.

Barra told his interviewer that he's totally blown away by the place. He said he had some charts to show why…

He said the Chinese are incredibly educated with 8 million college grads per year — more than the US.

Alipay is like Paypal in the US, except it's much bigger and more useful. Barra says he uses to pay for his cabs.

Weibo is like Twitter, except bigger. Barra only ever had 6,000 Twitter followers. In two months, he has 200,000 Weibo followers.

Barra says he runs his entire social life through an app called WeChat. He uses it instead of the phone, email, or text messaging. WeChat also has an Instagram-like feature.

The "Uber of China" is an app called Didi. Except with it, you leave a voice message for the driver telling him where to pick you up and how much you'll pay.

Barra said MoMo is an app you use to talk to strangers who are nearby you. It's kind of a dating app. It has 100 million users.

There's no Google Play store in China (it's banned), so there are a bunch of third-party app stores instead.

One is called "91." It's a desktop app like iTunes. Big Chinese search engine Baidu bought it for $1 billion last year. Hugo Barra

Barra says he loves China, and is trying to learn to speak the language. Here he is at his favorite dumplings place.
