On this day, 120 years ago, May 10, 1905 (April 7, 1905, the Chinese lunar calendar), Shanghai's industrial and commercial circles opposed the renewal of the "U.S. Treaty." Zeng Zhu, initiator of the Shanghai industrial and commercial circles 'boycott of American goods On May 10, 1905, the Shanghai industrial and commercial circles held a conference to oppose the long-standing discrimination and abuse of overseas Chinese and Chinese workers in the United States by the United States. In addition to directors of the Shanghai General Chamber of Commerce, Yang Shiqi, right-hand member of the Ministry of Commerce, and Chinese and foreign journalists attended the conference. The conference first passed two bills. One was to oppose the government's renewal of the new treaty with the United States because the Treaty on Restricting Chinese Workers Coming to the United States and Protecting Chinese Living in the United States expired; The second is to set a deadline for the U.S. government to delete and amend the Chinese Exclusion Act and treat Chinese workers and Chinese businessmen fairly, otherwise it will boycott American goods. The conference was led by Zeng Zhu, President of the Shanghai General Chamber of Commerce, and sent a telegram to the Ministry of Foreign Affairs and the Ministry of Commerce to "appeal for stern refusals and press charges"; in addition, it also called chambers of commerce in 21 commercial ports across the country, including Hankou, Tianjin, Chongqing, Nanjing, Guangzhou, and Changsha, to request concerted action; proposed specific boycott measures, mainly including: 1. All American goods, including machines, are prohibited;2. The use of American ships is not used for transporting goods; 3. Chinese children are not allowed to study in schools run by Americans;4. Chinese people are not allowed to serve as compradors, interpreters, etc. in American commercial companies;5. Encourage Chinese servants, coachmen, etc. hired by beauties to strike. Because of Yang Shiqi's opposition, the conference changed "banning" to "warning not using American goods" to show that this was a non-governmental activity and had nothing to do with the Qing government. Because the United States refused to change the contract and the suppression measures were implemented as scheduled, a vigorous campaign to suppress American goods was launched across China.
