Shanghai Huatan Communication Technology Co., LTD., founded in 2008, has been engaged in the research and development of mobile intelligence education. Based on more than ten years of mobile learning practice, we have developed mobile intelligence learning system and smart desk through technological innovation with natural interaction as the core.
