Hi @BudionoS , Thank you!
In 2020, I visited China. At that time, I had a transit at Singapore Changi Airport while traveling from Bangladesh to China. During the transit, I explored some parts of the airport and experienced the Skytrain.
InshaAllah, on my next trip to Singapore, I will explore this beautiful airport more thoroughly and visit some famous landmarks of the country as well.
