just in case, u want ur kid to be steady poon pee pee in his/her studies, well some one send me this amulet and asked me to use it on the spider spirits. but i think it's more for enhance brain juices of the ever kiasee parents with their kiasu studying kids.
i think hor, u print out this talisman and burn and then put it into water and ask ur already brilliant kid to drink.
