Suzhou has a long history of brick and tile manufacturing. Suzhou Tucheng was built in the Warring States period, and a few gates and water gates have been built with brick and wood. In 922 AD (the second year of Liang Longde in the Five Dynasties), when Yue was in money, the walls of Suzhou were all made of bricks. According to historical records, the brick city built in Qian is twenty-four feet high and twenty-five feet thick, which is very grand and magnificent. Bricks and tiles in Suzhou in the Tang Dynasty were very developed and widely used in urban and rural residential buildings. Suzhou's industry and commerce were extremely prosperous in the Ming Dynasty, and the brick and tile manufacturing industry was also very developed. At that time, the brick and tile industry was mostly concentrated in the area of Beidi Tomb. According to the physical data unearthed in Hengshan Mountain, Wuxian in the second year of Guangxu, there was a brick kiln in the tomb in 535 AD (the first year of Liang Datong), and 50,000 imitation copper finches were burned.

During the Yongle period of the Ming Dynasty, Judy, the founder of the Ming Dynasty, moved the capital to Beijing to build the Forbidden City. On the recommendation of craftsmen from Xiangshan School in Suzhou, the Ming Palace sent officials to Suzhou Land Tomb (now Lumu) to supervise the production of gold bricks. Because the yellow mud in Lumu Town is suitable for making bricks, and the technology is exquisite, the firing is excellent, and the technology is unique, and the gold bricks made are delicate and hard, "knocking loudly and breaking without holes", so Emperor Yongle named Lumu Brick Kiln as "Imperial Kiln".

The royal kiln bricks were placed in the Hall of Supreme Harmony, the Hall of Zhonghe, the Hall of Baohe, Tiananmen Gate and Dingling, one of the Ming Tombs in the Forbidden City in Beijing. These generous bricks are also marked with the year numbers of Yongle, Zhengde and Qingganlong in Ming Dynasty and the words "Governor of Suzhou".

Official kiln brick is a wonderful work of China sintered brick industry. Since the Ming and Qing Dynasties, it has been favored by emperors of past dynasties and has become a special product of court buildings. By Jiajing in the Ming Dynasty, brick burning had reached its peak. After the end of the Qing dynasty, due to years of war, the production of BRICS was intermittent and disappeared. But for a long time, the tradition of burning bricks and making tiles in Yuyao Village has been passed down from generation to generation. Nearly 600 years have passed since 14 13 imperial kiln fired gold bricks.

The firing process of ancient gold bricks is extremely complicated, which is briefly described in the famous Heavenly Creations of Ming Dynasty. In 1980s, after being lost for more than 70 years, Suzhou Lu Tomb Imperial Kiln began to rescue the golden brick firing process, mainly relying on the experience handed down orally by the ancestors of the kiln family. After years of hard work, this traditional craft has finally "revived". 1990, the newly fired brick was used for the first time in the maintenance of the Forbidden City in Beijing.

After 600 years of vicissitudes, the ancient imperial kiln is now thriving again. More than 1 10,000 bricks, bricks and ancient building components produced by Imperial Kiln are not only used in ancient building restoration and antique building projects all over the country, but also exported to the United States, Canada, Japan, Australia, Singapore and other countries and Hong Kong and Macao regions in China.
