Wu Gang, who used to operate an IT company in Sichuan province, chose to stop his company to take his son to Dali, Yunnan province, to be taught at home, after his child was not willing to go to school. Wu's son, now 15, is self studying natural and social science and holds an insightful view on some problems, which Wu believes is due to home lessons being an effective and relaxed way of learning. He also believes teaching at home will give his son more free time to practice study and make friends, as well as to expand his views.
