Founder Zhang Hao, Hao Ge, graduated from Xiamen University School of Management with a master's degree. In 2004, in order to raise 654.38+10,000 yuan to buy a car for his elderly father so that he could go to work before retirement, he began to make money as a tutor. With the growth of family education, he resolutely decided to start a business. On April 2, 2005, KLOC-0, a registered Happy Learning Education Consulting Studio was established, later called Happy Learning Education Technology Group. After 10 years of efforts, Happy Learning Education Technology Group is the largest extracurricular tutoring institution in primary and secondary schools in the southeast coast, training more than 20,000 students every year and earning hundreds of millions of RMB.

However, based on the drawbacks and contradictions of the real education industry and a deep understanding of the Internet, I resolutely embarked on the road of starting a second business without regrets and founded a crazy teacher. He said, "This is my second venture, but it is not a reinvention, but a natural extension and upgrade. We are not welcoming, but fully embracing the wave of online education because we have a big dream. "
