Letter to Captain Butler on the Anglo-French Expedition to China is an article with the background of the war of Anglo-French invasion of China. Captain Butler wanted to take advantage of Hugo's illustrious reputation to make him champion for the so-called victory of the Expedition to China, but Hugo, an upright writer without narrow nationalistic sentiments and representing the conscience of mankind, strongly condemned the brigandage of the Anglo-French allied forces' fire-bombing of the Yuanmingyuan in this letter. Hugo's remarkable thing is that his position is not narrow nationalism, but the position of mankind, he openly rebuked the robber government inverted black and white, not ashamed, but proud; also lies in his cherish human civilization achievements, respect for human civilization creators. His insight that "everything created by the ages belongs to mankind" is very penetrating. He praised the Chinese nation as a "superhuman nation" and expressed his sympathy and respect for the Chinese people. Hugo, the famous French writer, took a very clear position and a very distinct attitude towards the expedition of the British and French armies to China. He angrily condemned the Anglo-French allied forces of banditry, angrily condemned the Anglo-French allied forces of the destruction of the world's miracle of the Yuanmingyuan crime, he y sympathized with China suffered an unprecedented calamity.

Captain Butler wanted to capitalize on Hugo's prominence and get him to support the so-called "victory" of the expedition to China. But Hugo, a writer of integrity, was not narrowly nationalistic; he represented the conscience of mankind, a clear distinction between right and wrong, between love and hate.

The Anglo-French expedition to China, invasion and invasion, looting and plundering, destruction and destruction, the nature of the original is clearly distinguishable. However, as a Frenchman, it is easy to be blinded by the public opinion created by the authorities, easy to be dominated by narrow patriotic fervor. Hugo's sober mind, upright conscience, and impartial position are invaluable.

What makes Hugo rare is that his position is not narrowly nationalistic, but human. He was able to distinguish the government from the people, "the government will sometimes be robbers, but the people will never be robbers", the robber government can not represent the people, the French people are friendly to the Chinese people, the burning of the Yuanmingyuan is the crime of the British and French governments, and he stood on the position of the people to protest against the crimes committed by the government. He pointed out that this robber government had turned black and white upside down, and was not ashamed, but thought it was honored, and was brazen. It took great courage for him to publicly denounce the robber government.

The reason why Hugo is invaluable, but also because he cherished the fruits of human civilization, respect for the creators of human civilization. He pointed out that "everything created by the years belongs to mankind." This insight is very thorough. Although the Yuanmingyuan was a royal garden at that time, in the final analysis, it belonged to all mankind. Precisely because he cherished the fruits of human civilization, he had great respect for the creators of civilization. He praised the cultural and artistic value of the Yuanmingyuan, the creator of this world miracle, and the Chinese people as a "superhuman nation". This letter not only expresses his sympathy for the Chinese people, but also expresses his respect for the Chinese people.
