Dear Vladimir Putin(cái này vì mk thích nhá, bạn có thể đổi),

I hope this postcard finds you well. I am currently in Hanoi, Vietnam and I must say, it is an absolutely amazing city. From the bustling Old Quarter to the peaceful lakes and parks, there is so much to explore and discover.

I have spent my days wandering the streets, trying the delicious local cuisine, and immersing myself in the vibrant culture of this city. The people here are incredibly friendly and welcoming, and I have had some truly unforgettable experiences.

One of my favorite spots has been Hoan Kiem Lake, where I have enjoyed watching locals practice Tai Chi in the mornings and taking leisurely walks around the perimeter of the lake. Another highlight was visiting the Temple of Literature, a beautiful complex dedicated to Confucius and the pursuit of knowledge.

I wish you could be here with me to experience all of this firsthand. But for now, I hope this postcard gives you a glimpse into the beauty and charm of Hanoi.

Take care and see you soon!

Best regards,
(tên bạn)
