Online education company striving to reach a larger audience

The online education conglomerate iTutorGroup celebrates its 21st anniversary this year. But to the group's founder, chairman and chief executive officer Eric Yang, every day remains a new challenge.

"Every day is like a battle. Mistakes cannot be avoided. What we did right yesterday may not be applied today," he joked.

But jokes aside, iTutorGroup has grown into a benchmark in the online education industry. Even leaders in other industries such as e-commerce juggernaut Alibaba and insurance giant Ping An have strategic investments in iTutorGroup.
