The Merlion is the heraldic animal of Singapore. The story tells that the sultan saw a lion when he arrived in Singapore and therefore called the island "Singapura" = lion city (Sanskrit). There have never been lions in Singapore (now you can find some in the zoo), but who cares! The tourism board decided several years ago that a normal lion is not special enough, so they invented the merlion - and now you can find it at several places in Singapore.
Yes, Feng Shui is important in Singapore. See the buildings of the financial district (first row)? The building on the left has an odd shape, a bit like a sail. And guess what: it is meant to look like a sail! It will sail the whole district towards prosperity (they hope). The maximum height of buidlings in Singapore is 300 m. Surprised that the three highest buildings are 288 m high? This is because ba (eight) sounds nearly the same as fa (prosperity). Therefore 8 is the lucky number.
Ufos in Singapore on the picture in the second row? No, this is just the Supreme Court. The white building at the river is one of the oldest in Singapore, this is also the place where Sir Raffles landed in 1819.
