Standing out among more than 3,000 booths at the 2025 Autumn Fair, held at the National Exposition Center in Dong Anh commune (Hanoi), the Tuyen Quang booth was designed in the style of the northern uplands, decorated with motifs of the H’mong and Tay ethnic groups. Featuring over 100 OCOP items and distinctive agricultural and rural products, it attracted a large number of visitors who came to explore, enjoy tea, and buy specialties.

Cao Duong hamlet is located at an altitude of nearly 1,000 meters with a cool climate all year round, bordering the Cham Chu special-use forest. In September, when the rice begins to ripen, the Ripen Rice Festival is held. The golden terraced fields, soft and winding like silk strips across the mountainside, create a majestic natural painting that attracts many visitors.

Trang Da persimmon (Nong Tien ward) is recognized as a 3-star OCOP product. The harvest season lasts from late August to September each year. The ripe persimmons are red and juicy. Their skin is as thin as silk. Once tasted, the sweetness melts on the tongue, offering a delightful taste experience to diners.
