For a long time, tin industry has occupied an important position in Yunnan's local economy. Gejiu tin mine has a long history, and it was extensively mined in Qing Dynasty, with an annual output of more than 7000 tons 19 19. However, the production of Yunxi has always adhered to the law in mining, mineral processing and smelting, and there has been little improvement. Because the color does not meet the requirements of international standards, it has to be transported to Hong Kong for refining, so that the rights overflow and are controlled by others.

Founded in 1905, Gejiu Tin Company evolved from "Gejiu Factory Public Service Company". Due to poor management and lack of its own technicians, it was trapped at the mercy of Pei Laolu, a German engineer with poor skills in Liyang Company.

Miao Yuntai (Zi Jiaming) studied in the United States, majoring in mining and metallurgy, and returned to China on 1920. When he was an engineer in Yunnan Tin Company, after careful field investigation and study, he put forward his opinions on rectifying the old tin industry at 192 1. Tang appointed him as the general manager of Tin Affairs Company to rectify production. He presided over the restoration of sand washing plants and refineries that had been abandoned for many years and their parts had rusted and fallen off; Moreover, the overhead iron cable which was originally installed in Lanshe Cave and had no sand to transport was moved to Malage Mine, and the ore was directly sent to the sand washing plant, which changed the original mining and transportation mode and greatly improved the output. Rectify the debt relationship with Fudian Bank and Oriental Credit Union Bank, and re-establish the credit relationship with the bank, so the company's profit gradually increased, from-16 143 yuan in the first year of the Republic of China to 192 1 year in the first year of the Republic of China, and the profit was11year.

President of Fudian New Bank

Since the Revolution of 1911, Yunnan has spent years protecting the country and protecting the law, and its financial situation has become increasingly difficult. The Yunnan provincial government held a meeting to discuss how to rectify finance and increase income. Some people follow the routine and advocate increasing salt tax, land tax and lijin. Miao Yuntai objected. He said: "People are like cows. Cows are almost drained of milk and can't be milked any more." He also suggested setting up a special import goods donation bureau to collect special donations of imported goods such as foreign yarn, foreign cloth, foreign medicine and foreign oil, and obtained the consent of the authorities. In this regard, foreign businessmen protested, but Miao Yuntai was unmoved. As a result, the local authorities in Yunnan made a large sum of money and prepared to rectify Yunnan's finances and open a new Fudian Bank. After the establishment of Fudian New Bank, due to the political turmoil and economic depression in Yunnan, Fudian New Bank was struggling.

France had a certain sphere of influence in Yunnan at that time. The local foreign exchange collection business is also monopolized by the French merchant Agricultural Credit Bank. They use the Yunnan currency earned by customs declaration agents to exchange foreign exchange from China exporters and do unprofitable business. The bank has a branch in Mengzi, Yunnan and an office in Kunming. The bank not only controlled Yunnan's foreign exchange, but also issued Vietnamese currency, which seriously damaged Yunnan's finance through Fuzhou (now Funing County), Guangnan and Wenshan. At this time, at the suggestion of Miao Yuntai, the Yunnan provincial government issued an order in May 1933 prohibiting the use of Vietnamese currency in Yunnan Province. 1934, when Fudian New Bank was about to close down, the relevant departments in Yunnan asked Miao Yuntai to be the president of the bank.

Fight bravely for the country and the people.

Miao Yuntai stopped business for three months after he became the president of Fudian New Bank. First, the opium warehouse was cleared and the opium business office was cancelled. Subsequently, Miao Yuntai implemented foreign exchange management and adopted the method of "documentary foreign exchange" to attract an old factory owner to sell the foreign exchange obtained from the sale of Daxi to Fuhang. Pay the manufacturer a sum of money first. After the manufacturer sells Daxie, foreign exchange can only be sold to Fudian New Bank, but not to Credit Suisse Oriental or other foreign investors. After the implementation of Miao Yuntai's foreign exchange management measures, the interests of the French Agricultural Credit Bank were seriously damaged. They ordered the coastal defense customs to control the transit Yunnan export goods through the French governor in Annan (Vietnam), which caused great difficulties for the export of Yunnan goods.

Miao Yuntai opposed the plan of Yunnan authorities to make concessions to Oriental Credit Union Bank. He said: "The Yunnan-Vietnam Railway was built in the thirty-fourth year of Guangxu in Qing Dynasty. The French stuck us with the railway, which only forced us to return to the days thirty-four years ago in Guangxu. We can carry big tin with livestock, but the French can't beat us. " Due to the sharp drop in railway freight, Miao Yuntai's tough attitude has greatly affected the income of Yunnan-Vietnam Railway Company. Finally, the Yunnan-Vietnam Railway Company intervened, and the French Agricultural Credit Bank said that it would not interfere with the foreign exchange management measures of Fudian New Bank, while Fudian New Bank supplied the foreign exchange needed by the Yunnan-Vietnam Railway and the French Agricultural Credit Bank at preferential prices.

In the autumn of 1935, the French Agricultural Credit Bank accepted the foreign exchange control policy of Fudian New Bank, and the struggle was completely won.

War of Resistance against Japanese Aggression helped repair the Yunnan-Myanmar Highway.

1937 after the outbreak of War of Resistance against Japanese Aggression, Miao Yuntai and other Yunnan patriots realized that China-Myanmar highway should be built to strengthen the supply route of War of Resistance against Japanese Aggression. At that time, although Myanmar had established an autonomous government, the power was still in the hands of the British.

Miao Yuntai held several consultations with the British Consul General in Kunming, and then went to Yangon to hold talks with Glenn, head of the British Secretary in Myanmar. At this time, the highway from Kunming to Shimonoseki near Dali has been built in western Yunnan, and the wonderful railway from Yangon to the summer resort has been built in Myanmar. Therefore, the project of Yunnan-Myanmar Highway actually extends from Shimonoseki to Wan Ding, and Myanmar is built from Meimiao to Wan Ding.

During the negotiations between the two sides, the British General Staff expressed doubts about our ability to build a highway from Shimonoseki to Wan Ding. In particular, I don't believe that our project can be completed within one year. Miao Lao confidently gave a positive answer. Finally, the two sides reached an agreement. In order to understand the difficulty of road construction, Miao Yuntai took a car along the dirt road, from Meimiao to mangshi, China, surveyed the terrain, and then returned to Yangon, urging Myanmar to start construction as soon as possible. Then immediately return to Kunming, report to the relevant departments of Yunnan Province, and ask to start work on the same day.

1938 The highway was finally completed, and 1939 was opened to traffic at the beginning of the year. This is the achievement of Qian Qian's tens of millions of migrant workers with patriotic passion, and Miao Yuntai has also contributed his own strength.
