Your new local habits in Taiwan

Friendship with benefit

Arguably the same across the world except to different degree, but newcomers to Taiwan should know that "true friendships" are hard to find here. That means most Taiwanese won't befriend you without ulterior motive. And even Taiwanese will occasionally confess to being inclined to take petty advantages of people. For example a female Taiwanese friend asked me casually to translate short copies from Chinese to English, knowing she would not pay for my intellectual labor.

Even large firms will "take advantage" of long-term hires to rip them off of pensions. I've seen it first-hand.

One form of such "friendship with benefit" is that you may be invited to weddings of coworkers and friends you barely know for it's customary to offer cash in red envelope as gift. 

Another "custom" in Taiwan is corporations being widely dishonest and misleading when hiring. In short new hires will find extra duties not stated in want ads.

Yet another "custom" in the local corporatedom is patronage. Incompetence and corruption are widely overlooked and patronized. Whistle-blowing is generally not popular in Taiwan.
