Hanyuan, the hometown of pepper in China, was a special tribute pepper for the royal family in the Tang Dynasty. The authentic Hanyuan pepper was named Qingxi pepper. The local dialect was Qingxi pepper, which was only produced in several townships in Qingxi District. Hanyuan pepper was selected and bred by hundreds of generations of Qingxi pepper farmers, and its gas was clearer, its taste was heavier, its fragrance was stronger and its hemp was stronger. Hanyuan was named "the hometown of Zanthoxylum bungeanum in China" by the State Forestry Administration in 200 1 year. In 2004, Hanyuan Zanthoxylum bungeanum, a must-have in Bashu, was officially listed as a national geographical protection product. In 2008, Hanyuan Zanthoxylum bungeanum ranked first among the "Top Ten Geographical Indications Agricultural Products" in Sichuan Province, and it was the only product on the list in Ya 'an. Authentic Hanyuan Zanthoxylum bungeanum, named Qingxi Zanthoxylum bungeanum or Niuxipo Zanthoxylum bungeanum, is only produced in several townships of Qingxi Town. The quality of pepper produced in other towns and villages in Hanyuan is worse. The pepper in Xichang, Luding and other places is not really Qingxi pepper. Due to the scarcity of resources, it is difficult to buy really superior Qingxi Zanthoxylum bungeanum or Niujiaopo Zanthoxylum bungeanum in the market. The bulk purchase price of local Zanthoxylum bungeanum is higher than the retail price outside. Just think about it and you will know the situation. Around 2000, many foreign bosses came to Jianli Township and bought millions of pepper seedlings to sell and plant in other places. Therefore, authentic Niuxipo Zanthoxylum bungeanum may also appear in different regions with the support of modern logistics level. However, even so, the quality of the same pepper variety cultivated in different places is very different. Anyway, Hanyuan Zanthoxylum bungeanum, a famous doll pepper, is produced in Hanyuan County.

According to the historical experience of local people in Hanyuan County, the best pepper in Hanyuan County comes from Qingxi Town, a high-altitude area in the north, and the best pepper in Qingxi Town comes from Jianli Township (the ancient name of Jianli Township is Niuxipo, hence the name). Therefore, Jianli Zanthoxylum bungeanum is the most famous in Hanyuan County. Jianli Township has always been the main producing area for royal tribute peppers, and there is also a precious cultural relic-the tribute-free monument, which records the story that the bureaucrats of Hanyuan County begged Emperor Guangxu to exempt the tribute for the people at the end of the Qing Dynasty. In addition to Hanyuan Zanthoxylum bungeanum as a signboard, many online stores also directly use Niuniupo Zanthoxylum bungeanum as a signboard. Hanyuan Zanthoxylum bungeanum has a long history and was listed as a tribute in the Tang Dynasty, hence the name "Gongjiao".
