口译练兵:"逃离北上广"英语如何表达

笔者的译文（仅供参考）：

Recently, there goes around among white collars a new catchphrase, “to flee BSG”. The initialism stands for “Beijing, Shanghai and Guangzhou”, three largest cities in China. Due to escalating housing price, difficult job hunting, and high pressure of “survival” in these cities, white collars start to flee the Neverland they have had in mind. They now move to second- and third-tier cities or back to their hometowns to “give respite to their youth”.

Though cases are reported on the media, no one knows exactly how many have left (or are leaving). By using the word “flee” to nail down their action, young white collars mean to voice their protest against the high home prices and high life pressure in big cities, but the action falls short of a trend. On the contrary, while some are leaving, still more people are pouring in. In this sense, big cities are really “besieged cities”.
