According to ancient historical records, Ke Mon village was established in the 14th century under the reign of King Tran Anh Tong. Ke Mon village is located next to Tam Giang lagoon and has agricultural land, so the residents here mainly live on farming and fishing.

In 1789, after defeating the Qing army, King Quang Trung established the capital in Phu Xuan – Hue and called for talented people to help the king manage the country. Mr. Cao Dinh Do, a native of Thanh Hoa, came to Hue to ask for a job in the goldsmith profession. When crossing the O Lau river, his whole family was in trouble. The people of Ke Mon saw this and helped them escape death. To commemorate the life-saving merit of the people of Ke Mon village, after entering the palace, Mr. Do returned and taught the profession to the people here.

Since then, more than 200 years have passed, and Ke Mon village has become the cradle of the goldsmith profession in the South. The goldsmith products here have met the needs of jewelry and decoration of residents and mandarins in the capital city of Hue since the end of the 18th century, thanks to many goldsmiths from the North, typically Mr. Cao Dinh Do from Thanh Hoa who settled in Ke Mon village to practice goldsmithing and opened classes to teach his descendants. The goldsmith products in Ke Mon are famous for their good quality compared to many other places with sophisticated craftsmanship and elaborate carvings made by experienced, skillful and creative craftsmen, most clearly shown on jewelry such as bracelets, necklaces, rings, bracelets, necklaces, and earrings made of gold or silver.

Over the past two hundred years, thousands of people from Ke Mon village have left the village and appeared, first in the capital city of Hue (to work in the Royal Guard), then in most of the cities, towns, and large markets of the country, and later on, spreading out to the world. The goldsmith profession became the livelihood of the people of Ke Mon, and the goldsmith profession from here spread throughout the country.
