Because when Li Hongzhang signed the treaty, he did not represent himself personally, but the entire Qing Dynasty. In addition, because of the humiliating nature of the treaty, Li Hongzhang was not willing to bear this crime, so he signed the treaty. The word "solemn" was added. When Li Hongzhang signed the "Xin Chou Treaty" that was humiliating and humiliating the country, he was actually extremely unwilling in his heart. However, because the emperor's order was hard to disobey, Li Hongzhang was forced to sign this treaty. This was also the last treaty in his life. .

Although Li Hongzhang signed this treaty, he did not represent himself, but the Qing Dynasty at that time. Therefore, after Li Hongzhang was ill at home for several days, it was because of the constant urging of the great powers that Li Hongzhang signed. And this character "Su" is actually the first character in Li Hongzhang's title. Li Hongzhang's title was "Su Yi Bo", and the word "Su" he signed represented the Qing Dynasty at that time. Although he was reluctant, Li Hongzhang had been involved in official circles for many years, so how could he not know that if he signed this word, he would have to bear eternal infamy. Therefore, in order to prevent future generations from blaming him, Li Hongzhang had no choice but to use his title to sign the treaty.

Although most of Li Hongzhang's surviving calligraphy works are vigorous and powerful, the words on the treaty are rather sloppy. In fact, this was probably Li Hongzhang's deliberate move. Because of his rejection of the treaty and the possible infamy, Li Hongzhang did it deliberately when he signed the treaty. Although Li Hongzhang was the Minister of Commerce and Industry, he was also the leader of the Westernization Movement. In order to make the Qing Dynasty strong and able to withstand foreign humiliation, Li Hongzhang also made many achievements in developing the national economy and military strength. Although Li Hongzhang held many positions, due to the decadent Qing Dynasty, Li Hongzhang suffered "eternal infamy". The series of unequal treaties he signed, and even the humiliating treaties that led to the decline of modern China, seem to have been caused by Li Hongzhang.
