I am no longer focus on left behind children because focus on that still does not solve any issue on discrimination. Discrimination came from government's decision, therefore my goal is the increase the possibility for rural migrants to go or survive in city legally.
And yes, left behind children still exist in China, but it is very small % in overall population development; only big organization have focus on such small portion of issue (such is UNICEF). In addition, Chinese children that does have any education (regardless of educations that are provided) are still consider higher than other developing countries in Asia.
After my research on reports and datas from un.org and worldbank.org, I realize that UNICEF and some big name NGO only presents the absolute poverty with the worst situation happened in China, they somehow ignore the average condition of China in reality.
