Mr. Lu Guobin founded Hunan Pingkou Teaching Equipment Factory in 1987. Lead the team to continuously develop and improve new products, launch new products such as flat and curved blackboards, upper and lower lifting blackboards and other new products to the market to meet different teaching needs and receive wide praise from the education community.

In order to explore the market and the company's development needs, Pingkou Teaching Equipment Factory was relocated to Tongzhou District, Beijing in 1999, and the company was renamed Beijing Kaitlun Teaching Aids Co., Ltd. The new regional environment, higher usage requirements and the advent of electronic teaching equipment have put forward higher requirements and challenges for teaching writing boards. Beijing Kaitlen has been constantly innovating in accordance with the needs of the times and has increased its product research and development efforts. It has successively launched its first universal blackboard in 2002 and a combined push-pull blackboard in 2003. The combination of the combined push-pull blackboard and current multimedia equipment presents and improves a new concept of modern teaching. The company's products quickly entered the national market. The thriving career, however, caused the then Beijing Kaitlen Teaching Aids Co., Ltd. to face a crisis due to a disaster caused by the company's leader Mr. Lu Guobin. At this critical moment, Mr. Lu Anbing took the lead in the company with his pursuit of education equipment.

In 2013, with love for his hometown, Mr. Lu Anbing decided to move the company back to Kaifu District, Changsha City, Hunan Province as a whole, and the company was renamed Hunan Yifan Teaching Equipment Co., Ltd. With the rapid development of "intelligence" in the field of education, Yifan's R&D team is also following the development of the times, working hard in the field of teaching writing boards and accurately positioning. A rail-changing pure plane push-pull writing board was developed in 2017. After it was put on the market, it received high praise from the education industry and once became a new highlight of the industry. In the extraordinary period of fighting the epidemic in 2020, Yimo Ren has always insisted on pioneering and innovating, and has developed and launched a smart connection blackboard that integrates with elements of the Internet era. Push traditional writing boards to a higher area.

In accordance with its own development requirements, Hunan Yifan moved into the new factory in Phase II of Zhuoda Industrial Park, Xiangyin Section, Furong North Road, Changsha City in April 2020.
