Sry, I'm only familiar with the route of bus 31. If you take bus
31, u come out from the mrt, I'm not so sure to turn right or turn
left from the mrt station but if I do not remember wrongly, turn
right after you exit and you come to this bus stop just outside the
station. Further down the road you can see those places where they
frow and sell flowers. After taking bus 31, it brings u directly on
the oppsite side of the ite and you just cross the overhead bridge
to reach it.
Don't worry too much lah, u will see a lot of them in the same
uniform as u when u reach tanah merah mrt.
Sry if my memory doesn't serve me well. Too long never go there
liao.
