A trip to Singapore (NO.2)

I always go abroad with heavy baggage, because I read many books in the flight and the hotel.
I read 16 books during this travel.
It is difficult for me to go like a backpacker.
“Go abroad with books” is my trip style.
One of the purposes in this Singapore trip was to buy English books.
English is the main official language in Singapore.
And the intellectual level of Singapore is high.
I must be able to find good book stores there.
