Since October 2010, Gu Nai International has launched a public welfare fund to support impoverished mountainous areas such as Yunnan Erdong Primary School and impoverished families, providing warmth to students and elderly people in impoverished mountainous areas. Everyone contributes a share of love and everything is improving. For many years, Gu Nai has never been absent. The rugged mountain roads, dilapidated classrooms, and bumpy playgrounds have now become cement roads, newly built teaching buildings, renovated activity venues, and provided living materials.
