I think I'm in China-land

After being in the office for only 2 weeks, I feel as if I am working in China. Almost everybody around me communicates in Chinese. As a matter of fact, I am confident that more than 90% of the people around me speak Chinese as a native language. Left, right and back - all Chinese. Even the managers speak Chinese. The only person who doesn't communicate in Chinese is the petite lady in front of me; only because she is not of Chinese descent. And when they come up to me, they automatically assume that I speak Chinese. Why are most accounting & finance departments dominated by Chinese? Is this the same at your place of employment? It scares me. Whatever happened to cultural diversity?
