Google's Go-playing computer program AlphaGo claimed a historic victory in the ancient Chinese boardgame over Go grandmaster Lee Sedol of South Korea in March. The computer program won four games to one in the best-of-five series.

The victory has fuelled a growing interest in artificial intelligence and boosted Chinese companies' investment in the sector.

New tax on imported e-commerce purchases

Mobile apps make purchases easier

More Chinese consumers preferred to make payments via smart devices as mobile apps make purchasing much easier, a PwC report found.

Nearly one-third of respondents in China opted for mobile payment when shopping last year, doubling from 16 percent in 2014, according to the accounting firm's global retail survey. The figure appeared much higher than the world's average of 12 percent.

The popularity came as a result of explosive growth of mobile payment options and an expanding mobile network.

Fenda was launched in May by website, Zaihang, a platform for people who want to learn knowledge and expertise online.

There were more than one million paying customers on the app within the first three days after it launched, according to the Zaihang website.

Bike-sharing gets popular

Mobike and ofo, which allow people to use an app to locate and borrow available bikes nearby, get popular among young urbanites.

Since August, the Beijing-based Mobike, has landed four rounds of financing, totaling hundreds of millions of dollars. But its record is not unique, as its cross-town rival ofo has also pulled off fundraising four times. According to a report from Bloomberg, ofo is valued at $500 million, an unusually large size for a company that is just 2 years old.
