Thanks to Thomas Tse , my good friend in the university, solve the main technical problem. Lighthouse Philately is the collection of lighthouse stamps and any other philatelic items.
Some people say philately is stamp collecting.
We buy stamps from post office or from stamp dealers, then put them in the stamp album. This ended the 'whole process'. But I don't agree with that. Philately is on one hand 'collect philatelic items' and the other hand 'collect philately knowledge'. It's 'Give out heat and light' by Sammie Cheng, a famous pop singer in Hong Kong.
