✔ 最佳答案
Spanish. It's the language of poorer people and would give them an advantage, and it has vocabulary and grammar in common with Portuguese, French, English, Italian and other languages, making it easier to learn. It's also less imperialist than English. Chinese is an easy language but the number of people who can speak it other than the Han is too small for it to be truly international. One solution might be to *speak* Spanish but write it in hanzi.
