Relationships and connections — the network that gets things done.
Literally just "relationship," but in business it means the web of reciprocal obligations that opens doors. Having 关系 can matter more than qualifications. It is also the ordinary word for how two things relate.
English business books treat it as exotic. In daily Chinese it is a completely ordinary word — do not over-perform it.
Reading a definition isn't the same as saying it to someone. Lingo Kaiava is a voice tutor set to Chinese — it uses 关系 the way locals do, corrects you in the moment, and never "fixes" the way real people actually talk into textbook Chinese.
