I last time sec 1 very anti social. I dont talk to ppl and
always eat by myself till the teacher have to go up to me and ask
me if anything is wrong. 
But now, almost the whole level is my friend.
Take things slowly. And most importantly dont look too desperate.
Cannot let others know that you cannot live without friends. By
doing this, you gain their respect and also the need for them to
gain your trust to be your friend.
Secondly. Be wise.
Make sure you know the latest news like some kind of disaster or
what kind of environment do china ppl live in. And best if you know
the best place to hang out or the place which provide the most
valuable offer for pool or k box.
Thirdly. Lying.
You must know the trick of lying. Sometimes in secondary school,
you cant go ard telling the truth. Or u will either find a pig head
hanging outside your hse the next morning or you will end up in the
icu.(for extreme cases only) Tell one story to A. Dont say the same
thing to B. This is a tricky but good way of survivng in secondary
schools. But beware, if other ppl see through your trick, be
prepared to spend the rest of your days in hell.
Fourth. Knowlegeable.
Make sure you know the backgrounds of your teacher. Like how many
kids she have, whats her husband occupation. How chio is his wife,
He everytime go where clubbing.
