Problem: Please answer a question about the following article about Qing dynasty:
Chinese generals and officials such as Zuo Zongtang led the suppression of rebellions and stood behind the Manchus. When the Tongzhi Emperor came to the throne at the age of five in 1861, these officials rallied around him in what was called the Tongzhi Restoration. Their aim was to adopt western military technology in order to preserve Confucian values. Zeng Guofan, in alliance with Prince Gong, sponsored the rise of younger officials such as Li Hongzhang, who put the dynasty back on its feet financially and instituted the Self-Strengthening Movement. The reformers then proceeded with institutional reforms, including China's first unified ministry of foreign affairs, the Zongli Yamen; allowing foreign diplomats to reside in the capital; establishment of the Imperial Maritime Customs Service; the formation of modernized armies, such as the Beiyang Army, as well as a navy; and the purchase from Europeans of armament factories.
