"may I know how to get the qian? do i need to pay to get anyone inside the temple explain the qian for me?"
u go inside the temple, there is a counter with lots of container. take 1 container and a pair of the 'bei' (a crescent shape thing). then go to the red carpet.
kneel down, in ur heart ask wat u want to knw, then throw the 'bei'. if one facing up and the other facing down, then u proceed to shake the container. otherwise rephrase ur question and throw the 'bei' again. until u get one of the 'bei' facing up and one facing down, u hv to repeat the process.
then u shake the container until one of the 'qian' drop out. then u throw the 'bei' again and ask if tis is the one. if one facing up and one facing down, then u may walk to the counter and show them ur 'qian'. otherwise, put the 'qian' back and repeat the process.
the counter ppl will give u a piece of pink color paper. if u can't read chinese, turn over there is english interpretation behind.
Good Luck!
