Along Telok Blangah Rd (near the flats)...there are several
idols inside, must pray to the yue4 sia4 lao3 ren2 (he's got red
strings draped over him), give a donation for the prayer oil and
make a wish.
When you found the one, must go back to give thanks - my mum asked
me to buy a cake. Later I took my SO there to give thanks also. PM
me if you need more info on the location.
