(Yicai Global) Aug. 15 -- Beijing-based primary and secondary education website Zybang acquired USD150 million in its C-round financing; the second round for the firm in a year and the largest in China's K-12 education sector.

The investment round was led by H Capital and followed up by Tiger Fund and other early investors, including Sequoia Capital, Legend Capital, GGV and Xiang He Capital, China.org.cn cited Zybang as saying on Aug. 14.

All of the proceeds from the funding will be used for teaching and education research with a focus on its live teaching brand 'Zybang Lesson 1,' said founder Hou Jianbin.

Zybang Lesson 1 is a live platform which aims to help students efficiently improve performance; it covers curriculums from primary school through senior high. The virtual classroom allows one-to-one teaching and the firm expects to provide 5 million minutes of teaching per month. Lesson 1 was one of the fastest growing online classes last year.

The company hopes to capitalize on internet technology and Big Data to deliver more quality education resources across the country, including remote rural areas, and encourage people to share resources, Hou said.

After setting up in 2015, Zybang now attracts more than 60 million live users a month and holds a market share of over 70 percent.
