China's first participation in the World Expo should have started at the Vienna World Expo in 1873, and China's participation mode is also a wonder of the Expo itself. Because the representative of China is an Englishman named EoCoBowra. It was neither the imperial court nor court officials who sent him to represent China, but Hurd, the State Administration of Taxation of the Qing Dynasty at that time. After 1840, China's customs and foreign trade were entrusted to foreigners. Hurd sent Paula to participate in Saiqi Expo on behalf of China in order to expand China's business ties with foreign countries and gain more profits.

For the first time, the China government sent its own representative to participate in the World Expo as a country. It was the Philadelphia World Expo in 1876. At that time, the representative of China's industry and commerce was Gui Li. He is a wise, brave, resourceful and courageous China man, but he was overwhelmed by that era. Gui Li wrote a book called "A New Record of Traveling Around the World", which recorded the 1876 Philadelphia World Expo. Although he is the only China person in the China delegation, it is the first time that China people have officially set foot on the World Expo.

So it should be a.
