Nowadays as all china'children can get basic education free of may wonder why the ability of self teaching is still of first importance. I'd like to air my views follws.
    Firstly.no matter how long you can stay at school,you must leave school sooner or later.Aftergraduation,you must go on learning something new on account of what experts call information explosion
and competition in society.You'll have to teach yourself,which is sa lifelong task.Secondly,even when you 're at school,you must depend on your own ability to learn more,trying to figure out the answers and decide the field of your interests.Teachers are not secretaries always following you,Last but not least,if you don't have the ability of self-teaching,you can only be a recorder or at most a computer always waiting for instructions.
    In short,as exploring new fields is a permanent challenge,self-teaching ability is of top importance.
