orh.. this one got a cute story behind it one. one day, guy A
went and buried 300 "liang" (money in old china) in his backyard.
and he dun want people to come and steal. so he write a sign board
and put there, saying, "ci di wu ying san bai liang (here got no
300 "liang")"
then his neighbour, Li Si, came, saw the sign and dug up the silver
and didnt want his neighbour to know it is he who stole it. so he
write next to the sign, "ge bi li si bu ceng tou (your neighbour Li
Si never steal)"
