There are four official languages in Singapore! There's Malay, which comes from the neighboring country of Malaysia, Mandarin from China, Tamil from India (one of the oldest languages still spoken in the world today), and English.
We use Singaporean dollars. One Singaporean dollar (S$1.00 or SGD 1.00) is about $0.78 USD!
A bottle of water can vary in price depending on the place you get it from. Be it from a local small shop or a stand on the side of the road, it may be S$1.30 - S$2.00. However, if you go to a nicer store or restaurant, it can range between S$5.00 - S$7.00.
Most definitely, malatang! Malatang a customizable Chinese street food and soup dish that literally means "numbing spicy hot [soup]."

I have been listening to jazz music and lofi while I study! It helps me focus.
