Around A.D. 1368, China people invented a special kind of tea, which is Fu tea. Because Hunan black tea was used as raw material at that time, it was named "Hu tea", and because the raw materials were sent to Jingyang for manual construction, it was named "Jingyang brick"; Because it is processed in dog days, it is called "Fu Cha". Later, because its fragrance and efficacy are similar to Smilax glabra, it is called "Fuzhuan Tea" and "Fuzhuan Tea". Because it was made by the government, 30% to 50% of brick tea was sold to the government as tax in Lanzhou in the early Qing Dynasty, which was also called "official tea" and "official tea". The remaining brick tea is sold by tea merchants according to the sales area designated by the government, which is called "attached tea". Because its utility is similar to Smilax glabra and its shape is brick-like, it is also called "Fuzhuan Tea" and later known as "Fu Cha" and "Fuzhuan Tea". Because it is made by the government, its purchase and sale are strictly controlled by the government, so it is also called "official tea" and "official tea". Fu tea is the earliest pressed tea in China, and it is also the most complicated, oldest and oldest bulk tea product.

Fu Cha tea is called "mysterious tea on the ancient Silk Road" because it contains magical "golden flowers" and is full of the ancient Silk Road leading to Central Asia and Rome.

Historically, due to the poor technology of pressing brick tea in Hunan tea producing areas, the quality of brick tea produced was loose and it was transported to the northwest many times, and the brick tea was seriously damaged. The purchased raw materials are transported to Jingyang for processing into Fuzhuan tea, which can not only reduce the damage of tea bricks, but also transport Fuzhuan tea to the sales market, which is more convenient than Hunan.

The official teas in the northwest of Ming and Qing Dynasties were all managed by Shaanxi Governor, and Jingyang became the place where tea was processed and inspected at that time. Processing Hunan raw tea into Fuzhuan brick tea in Jingyang is convenient for supervision and inspection.

1937 War of Resistance against Japanese Aggression broke out, and the huge amount of imported tea was greatly reduced due to the influence of traffic conditions, which aroused the great attention of the government at that time and asked local governments to solve this problem here. After scientific experiments and research, Mr. Peng Xianze, then deputy director of Hunan Tea Management Office, wrote an article entitled "Building a Brick in Anhua", which was published in the newspaper and attracted great attention from the government and people in the industry.

1May, 939, Peng Xianze was entrusted to Anhua to inspect black tea bricks. At that time, several sample bricks were pressed with a wooden press in Jiangnan Ping, Anhua (now Jiangnan Town) and sent to the Trade Committee of the Ministry of Finance for inspection. I received a reply in June: "The color and taste of the sample brick are good, but the brick body is loose and crushed." In July, six manual screw presses were ordered in Xiangtan, and the presses were shipped back in June 5438+February. 1940 1, and pressure began in March. According to Jingyang tea merchants who lived in Jiangnan Ping at that time, their products were: "Bricks are dense, bright in color and mellow in fragrance. Its quality is above Jingyang brick, tested by Chongqing Zhongcha Company, and sold by Zhongcha Company. Since then, Yiyang began to suppress black brick tea.
