Born in the Qing Dynasty, Zhang Mou was a servant of the Prince. Because he tried his best to flatter Yixin on weekdays, he was deeply loved by Yixin couple. He was promoted by Yixin and donated to buy off candidates. 1892, Tang, who was in charge of Kaiping Coal Mine, died, and Li Hongzhang appointed Zhang Yi as the general manager. Zhang Ji does not understand the management of modern enterprises; However, according to relevant materials, he successively owns 3,000 shares of Kaiping (i.e. 302,000 shares) and is one of the major shareholders. After he mastered Kaiping Mining Bureau, the yamen style of Mining Bureau became more serious.

19 In the 1990s, the production capacity of Kaiping Coal Mine kept rising, and the supply to areas outside Tianjin also expanded with the increase of output, from the original annual output of only about 20% to about 30%. In order to improve the transportation conditions of coal, besides its own ship transportation, the Mining Bureau also spent huge sums of money to open up Qinhuangdao Port. However, in view of all the funds needed to carry out this project, Zhang Yi has always adopted the way of raising funds to share shares in Kaiping Mining Bureau, directly using the property of the Mining Bureau as collateral and begging for loans from foreign forces. He borrowed 200,000 pounds of British gold (Pingyin 654.38+04,000) from British Merlin Company for the first time, and then borrowed 452,000 pounds from Dehua Bank. Before 1900, foreign debts accounted for about 44% of the total liabilities of Kaiping Mining Bureau. Borrowing foreign debt instead of attracting foreign investment is a major change that directly affects the development prospects of enterprises. It blocks the development opportunities of private capital, makes enterprises embark on the dangerous road of begging for foreign capital support, makes foreign aggressive forces easily penetrate into the key departments of enterprises, and seriously damages the independence of enterprises. Thus, in 1900, under the serious chaos of Eight-Nation Alliance's invasion, the coveted British invaders took the opportunity to collude with Zhang Yi and easily took away all the property of Kaiping Mining Bureau by deception and blackmail. Among the modern enterprises in China, this important coal mining enterprise has made great achievements, but it was finally plundered by foreign invaders.

Kaiping Coal Mine was originally the longest-running enterprise in Tang Dynasty. He personally presided over the coal mine from site selection, planning, fund-raising to formal mining. The annual output of this mine once reached the peak of 780,000 tons, which was beyond the reach of other government-run and commercial coal mines. As a part of it, there are Kaiping Railway, the first railway operated by China, and Tangshan Refined Cotton Factory, the first cement plant operated by China. These were also initiated and sponsored by Tang. If we compare Tang's mining achievements with the corruption and imbecility of his successor, Zhang Yi, the world difference between them will be obvious.

Zhang Yi's failure in managing Kaiping Coal Mine shows that "talent is the foundation of career". The quality of enterprise management depends to a great extent on the talents of the enterprise and on the managers who know both business and management. The failure of Kaiping coal mine in the later period is inseparable from the treacherous mediocrity of Zhang Yi, the mine manager. Zhangye mining industry has become a historical relic, but the lessons of its failure still have practical significance. This lesson can be summed up in a sentence from Mencius: "Without sages, you will die."
