hi orange,
try to be an active volunteer about 1 year before you register for your kids but take note that if you are going for ai tong and tao nan, you need to be membership for 4 years and above, living within 1km AND an active member, then you can go for phrase 2b, if not, dun bother cos i meet other hokkien huay kuan mummies who told me must meet all 3 criterias. Not to forget, in order to go for phrase 2b, you need someone from committee in hokkien huay kuan to endorse your phrase 2b form if not even if you quality for phrase 2b registeration, no signature from the committee or management to endorse, you might not even qualify for phrase 2b even if you are not going for tao nan and aitong.
It is a very long tedious process cos not only join volunteer work (might need about 8 hours on sun if there is event and need volunteer),must spend money and join in the activities they have(different from volunteer), must make sure within 1km AND NOT 1-2 kim
