When putting down roots in a foreign land, learning the language is the first and foremost prerequisite for blending into the local environment. If you can't speak English well, even if you have a lot of ability, you can only stay hidden within your own small circle of friends; no matter how learned you are, your skills will go unappreciated.
在海外要落地生根，語言是融入當地社會的先決條件，若講不好英語，能力再強，也只能躲在自己的小圈圈內，空有滿腹經綸，感嘆懷才不遇。
