In reality, it was not easy to be proficient in multiple languages, unless one is born with language talents. To be able to master two languages was already a good accomplishment, such as English and Chinese.
Both English and Chinese are extremely important in this world, since these two are the most communicated languages worldwide. As a matter of fact, English is a compulsory subject in China and Chinese subject for European countries.
Of course there are many other languages other than English and Chinese, such as French, German, Russian, Arabic Korean, Japanese and many more. Even though they are not widely used in Chinese or English, but those languages are indeed some tools for showing off, especially when only a minority of people knows how them.
Anyway, it would be quite impressive if one could spend tremendous effort to master a couple of languages solely to show off.
Yu Shengfan is complete!
