Kangba is located in the center of the ancient tea-horse road. Influenced by this environment, it first changed the concept of attaching importance to agriculture and neglecting business, and developed the habit of doing business. Kangba businessmen are smart and capable, which is well known.

in addition, many trading markets, distribution centers and accommodation points for backpackers and business travelers on the ancient tea-horse road have gradually formed towns for residents to live in during the long-term business activities. It has promoted the urbanization development of Tibetan society.

For example, in the desolate ravine of the Yuan Dynasty, after the opening of Diaomen and Yanzhou Chama Road in the Ming Dynasty, it gradually became a gathering place for the teams to the west of the Dadu River, and in the Qing Dynasty, after the opening of Vasgou Road and the construction of Luding Bridge, it quickly became a commercial center.

As a result, camel caravans from Tibet and other places outside the customs came and went in an endless stream, and merchants from all over the country gathered here to form a tea gang specializing in gold and musk. Qiongbu Gang specializing in cloth and Hada; Yam gang specializing in medicinal materials; Government goods gang specializing in silks, satins and leather sheets; Dried vegetable gangs specializing in food, and Yunnan gangs specializing in opium and groceries.

as a result, 48 pots and pans, 32 tea shops and dozens of firms dealing in different commodities emerged on the ancient tea-horse road. Emerging industries such as sewing tea, tanning, catering and hardware have emerged. Dwellings, shops, hospitals, schools, government offices and streets have been established one after another, forming a prosperous and lively town famous at home and abroad.
