Harbin north star was fast-paced and later renamed latitudinal. Founded in 2003 and founded by zhang li, a linguist. The brand founders took two years to develop the altitudinal and word speed method and then submitted a patent application, which was formally approved in 2009. After many years of development, the altruistic education has become an educational training institution with a wide range of activities, such as fast-tracking, calligraphy, examination, generation training teachers. The efficient writing method, harbin north star, has been based on the service concept of “let each chinese write chinese”, with the core task of “30 hours of writing”, targeting people of all walks of life, regardless of age, who need to improve their writing. On the basis of successful practices and deep understanding of writing education, zhang leah has pioneered the development of the science, application, simplicity and ease of learning of the north star's speed-of-writing method through the “latitude” and many years of teaching experience of a patent-based practice.
