Qinba is flourishing in March, which is the time when green tea is fragrant. At the beginning of March, the designated tea shop in Hanzhong, the main green tea producing area in southern Shaanxi, was uniformly replaced with the green tea garden gate logo printed with the words "Hanzhong Xianhao". Hanzhong is adjacent to Qinling Mountain and Bashan Mountain in the north, with a long history of tea production and superior ecological environment. The natural geographical advantages of "high latitude, high altitude, high probability of fogging and high content of zinc and selenium in soil" make Hanzhong tea market more and more famous. Since the end of 1990s, Hanzhong Municipal Party Committee and Municipal Government have regarded the tea industry as one of the key green industries, and strengthened their support and cultivation to make the tea industry develop rapidly. However, in the development process of Hanzhong tea, it has been caught in a long-term brand scuffle, with different standards, competing to reduce prices and difficult choices for consumers, which has hindered the tea industry from becoming bigger and stronger.

In 2005, the Hanzhong municipal government began the integration of tea brands, integrating the initial 20 brands into three brands: Wuzi Xianhao, Dingjun Mingmei and Ningqiang Quetongue. From June 5438 to February 2007, Hanzhong municipal government took the opportunity to apply for the protection of geographical indication products, and finally integrated the tea brand into a brand named "Hanzhong Xianhao". Hanzhong Municipal Government organized a delegation to participate in the first Xi 'an Tea Expo and the fifth China International Tea Expo, and "Hanzhong Xianhao" won many gold medals. Since 2008, Hanzhong Tea Industry Association has recognized the qualification of "Hanzhong Xianhao" as a designated production and marketing enterprise, and adopted the methods of "voluntary enterprise declaration, expert evaluation and certification listing", increased standardized production technology training, unified the signs of designated enterprises and stores, strengthened market supervision and standardized business order. Up to now, the city has identified 247 "Hanzhong Xianhao" designated production enterprises and "Hanzhong Xianhao" designated management enterprises 195.

Zheng, deputy mayor of Hanzhong Municipal Government, said in an interview with the Evening News reporter: "Hanzhong has vigorously promoted brand integration with the protection of geographical indications products, and Hanzhong tea is uniformly called' Hanzhong Xianhao'. Many, miscellaneous and chaotic brand problems that have plagued the development of Hanzhong tea industry for many years have been gradually solved, laying a good foundation for further expanding and strengthening Hanzhong tea industry.
