1.2. Thoai Ngoc Hau and the historical imprint on the Thoai Son region
Thoai Ngoc Hau, whose real name was Nguyen Van Thoai, was born in 1761 in Quang Nam and was a distinguished mandarin under the Nguyen Dynasty. He was entrusted with many important responsibilities and played a significant role in managing and developing the southwestern region of the country. His contributions are closely linked to the shaping of economic and social life in An Giang.
During his tenure as governor of Vinh Thanh, Thoai Ngoc Hau directed the excavation of the Thoai Ha Canal and the Vinh Te Canal, which helped connect waterways and support agricultural production. These projects expanded the cultivation area and promoted trade among the residents in the region. The impact of these works continues to influence local life to this day.
In addition to infrastructure development, he also participated in establishing villages, stabilizing the population, and organizing community life. His merits are remembered by the people, reflected in the construction of temples to commemorate him. The Thoai Ngoc Hau Temple thus carries profound historical significance, embodying the tradition of gratitude of the people of Thoai Son towards their ancestors.

As an artificial lake from an old project, the ecosystem at Thuy Tien Lake is not as diverse as natural ecological areas.

This intermingling brings a unique feeling to visitors who love natural spaces with minimal human intervention.
The landscape at Thuy Tien Lake changes at different times of the day, especially in the early morning and late afternoon.
