Dear ...,
How are you? I hope you are well.
I have visited HCM City and have just come back. Maybe you have known, HCM City, also called Sai Gon, it's the largest city in Vietnam. I went there with my best friend - Thu. At there, I stayed in a small hotel that my dad had booked. The weather is quite hot, but it's cooler than here! I love the food here because it's so bold southern character. People in here are very friendly.
I really like this trip. Next time, if it's possible, I'll invite you to go there with me!
Best wishes,
...
~HỌC TỐT~
