On this day, 151 years ago, February 21, 1874 (January 5, 1874 in the lunar calendar), the "Ma Jiali Incident" occurred. In the 1850s, after Britain invaded Myanmar, it tried to expand its power to the southwest of our country and plotted to build a railway from Yangon, Myanmar to Simao, Yunnan, China. To this end, in early 1874, Britain decided to send a huge pathfinder team to Yunnan, China. British Minister to China Wittomar visited the Prime Minister's Yamen for this matter. He falsely claimed that three or four officials were sent by the Indian colonial governor to "travel" to China from Mandalay and requested a passport. After the Prime Minister's Yamen agreed, Britain formed a 193-member armed "Pathfinder" led by Colonel Bai Lang. Among them are government officials, business officials, medical officials, and are equipped with officers, soldiers, and carrying new weapons. Starting from Mandalay, go north to detect land traffic in Yunnan and Myanmar. At the same time, British Minister Wei Toma sent Ma Jiali, translator of the Shanghai Consulate, to Yunnan via Wuhan and Hunan to enter Myanmar to meet him. On January 17 of that year, Ma Jiali joined up with the Bailang Pathfinder Team who had arrived in Bamo earlier. We set out in early February, hung up the sign of "travel" and crossed the border of China without authorization to invade Manyun in the Tengyue area of Yunnan. At the request of the gentry and people, Li Zhenguo, a general of Tengyue, Yunnan, deployed soldiers and soldiers to intercept foreigners in various key passes. On February 21, Ma Jiali and four China entourage arrived at Husong River. They were attacked by local people. All five were killed and their heads were hung on the Manyun City Wall. After this blow, the pathfinder team did not dare to move forward and retreated to Myanmar. The Magali incident was entirely caused by Britain's planned invasion of the southwestern border of China. However, the British envoy to China, Wei Toma, made a big fuss about this and finally forced the Qing government to conclude the "Sino-British Yantai Treaty" and obtained convenient conditions for invading the southwestern border of China. In 1875, at the north end of Bund Park, British overseas Chinese erected a monument to commemorate the murder of the explorer Ma Jiali in Yunnan. In 1909, the monument was moved to Bund Park;
