[5] At the age of 17, Sun Yuqi was admitted to Shaoxing Jianyi Normal School (Chinese: 绍兴简易师范学校) and graduated at the end of 1911.

In May 1915, angered by Yuan Shikai's acceptance of the Twenty-One Demands proposed by the Japanese government, Sun changed his name to "Yueqi" (Chinese: 越崎; lit.

They demanded the governor to send a telegram to Beiyang government, requesting the release of the arrested students in Beijing and rejection of the Treaty of Versailles.

With assistance from Cai Yuanpei, Sun enrolled in the Mining Department of Peking University, and graduated in 1921 with a bachelor's degree in engineering.

After graduation, Sun Yueqi returned to Shaoxing to recuperate for two years, during which his wife Ge Caixiang died of illness.

In September 1931, he transferred to Graduate School in Columbia University, and inspected coal mines across the eastern United States in the meantime.

[18] On his way back to China in the spring of 1932, he took a detour through Europe, spending about 40 days inspecting the mining industries in United Kingdom, France and Germany.

[19] He did not want to reside in Manchukuo under Japanese occupation, so after 20 days he and his family moved to Beiping (the name of Beijing from 1928 to 1949), which at the time was under the rule of the Nationalist government.

[5] In November, Sun went to Nanjing at the invitation of Weng Wenhao and served as commissioner and director of mining chamber in the newly established National Defense Planning Commission.

[30] At the Sixth National Congress of the Nationalist Party of China held in May 1945, he was elected as an alternate member of the Central Executive Committee.

As the Special Commissioner for the Northeast Region of the Ministry of Economic Affairs of Executive Yuan, he was sent to Shenyang to supervise the transfer of control of the heavy industries in Northeastern China to the Nationalist government.

At the same time, Sun Yueqi also served as the director of Enemy Industry Processing Bureau of Pingjin District in Hebei, with office located in Beiping.

In January 1947, Sun resigned from his posts in Enemy Industry Processing Bureau and Ministry of Economic Affairs, and moved to Nanjing to serve as the chairman of Resources Committee of the Executive Yuan.

[33] In July, Sun was tasked with inspection of industrial and mining enterprises affiliated with the National Resources Commission in Northern and Northeastern China.

When Chiang was in Fenghua District of Ningbo, he twiced ordered Tang Enbo to send telegrams to Sun, demanding the immediate demolition and relocation of factories to Taiwan.

Sun, with the support of acting president Li Zongren, refused to carry out the orders on the grounds that it would be detrimental to the peace talks held at the time.

[38] By the end of May, he resigned from his posts and arrived in Hong Kong, where he contacted Chinese Communist Party and received invitation to Peiping from Zhou Enlai.

Sun declined the invitation and contacted the Foreign Trade Office (Chinese: 国外贸易事务所) of the National Resources Committee in Hong Kong.

At the time, Foreign Trade Office kept tungsten, antimony, tin, mercury and other minerals in storage, with an estimated worth of US$6,000,000 (equivalent to $76,833,566 in 2023).

Under the leadership of local branch of CCP, Sun instigated the employees of the office to organize and resist orders from Ministry of Economic Affairs about the relocation of the mineral resources.

[40] The National Resources Committee was the only department among the central ministries that had organized protection of property when the Nationalist government withdrew to Taiwan.

Under Chen Yun's advice, Sun drafted an editorial titled No construction without engineering design (Chinese: 没有工程设计就不能施工) and published in the 16 June 1951 issue of the People's Daily.

In 1952, during the Three-anti Campaign launched by the CCP, he and other key personnels of the original National Resources Committee were detained and put under investigation.

[43] His old friend Lu Zuofu committed suicide during the Five-anti Campaign launched at the same time, and the news of the death reportedly overwhelmed him.

Sun accompanied the visiting British delegation led by the leader of Labour Party Clement Attlee to inspect the Kailuan Coal Mine.
