I was born and grown up on the poor land in Duc Tho district, Ha Tinh province. That’s where deeply attaches to me 24 years of life. If anyone who asks me that “What’s the thing your most proud of?” .I will answer that’s my hometown. Duc Tho is the land poor where the people live by rice cultivation, breeding, and fishing. Although the life is very difficult, but the people is very friendly, and studious. In Duc Tho, there is a Tung Anh village where called “Doctor village”. Duc Tho is also the home of Tran Phu Secretary General, and marked many memories of the great leader Ho Chi Minh.

If you come to Duc Tho, you will feel many interesting things, visiting Tran Phu tombstone, La Giang dyke, rowing on La driver, and enjoying the traditional songs. In the evening, they can enjoy a special food which is “mussel rice” – just only eat one time, you will never forget.

Beautiful and unobtrusive! Duc Tho always tries to grow, and to improve the life of people, but keeping the traditional culture.
