`终端 (zhōngduān)` vs. `航站楼 (hángzhànlóu)` for Airports: This is the most common mistake for learners. While “terminal” is the correct English word for the airport building, in Chinese, you almost
always use
航站楼 (hángzhànlóu). Using `终端` for an airport terminal sounds unnatural and overly technical, like something from an engineering manual.
