Why is "Deng Xiaoping's southern tour" trending?

Wikipedia Overview

Deng Xiaoping's southern tour, or 1992 southern tour (九二南巡), or simply Nanxun (南巡) was the tour of Deng Xiaoping, the third paramount leader of China, in southern China, including in Shenzhen, Zhuhai, Guangzhou and Shanghai, from 18 January to 21 February 1992. The talks and remarks made by Deng during the tour resumed and reinforced the implementation of his reform and opening up program in mainland China, which had come to a halt after the military crackdown on 1989 Tiananmen Square protests ordered by Deng himself. After Tiananmen Square incident, there was a lack of belief in the Chinese Communist Party both at home and abroad. The US and EU both issued arms embargoes while the World Bank and Asian Development Bank stopped issuing loans to China. The 1992 Southern Tour is widely regarded as a critical point in the modern history of China, as it saved the reform and opening up as well as the capital market, and preserved societal stability. It not only preserved stability inside of China, but it was reassuring to foreign countries who had begun to invest large amounts of money into China.
