Even landlubbers have to dive. It's so beautiful underwater The fairy coral I went snorkeling was good. Lily is a group with him, and the service should be just as good. Fairy coral is very private! The smallest house is 550 square meters (including the yard). I think Lily should be better.
Singapore Airlines is more comfortable (relatively speaking). In Singapore, you can travel around the city without a visa When choosing a flight, you should pay attention to the connecting flight for more than 5 hours, otherwise you will be in a hurry. Duty-free shops are actually the cheapest in Beijing (T3), but not in Singapore. The same thing (some cosmetics) is more expensive in Singapore than in Beijing. Accommodation in men, alas! It's small, but there are also big ones. I didn't stay in the original hotel (bigger one) when I went. I live in a small room, fortunately, only for one night, but the toilet is very big (relatively speaking) and there is nothing in it.
Just find a responsible agent, and the price is right! There are many sunny holidays in Beijing, but some are not good! There should be a lot of experience!
