Today, let's talk about a practical English expression — **Call it quits**.

Many people tend to interpret this phrase too simply, but its connotation is quite interesting. "Call" here doesn't mean "make a phone call," but rather "announce" or "make a decision." "Quits" is a somewhat old-fashioned word, originally meaning "a tie, offset, or complete end."

When combined, the core meaning of **"Call it quits"** is "to declare a conclusion or to voluntarily end something." Note that this emphasizes **initiative and mutual agreement** — it's not about being forced to stop, but rather calmly saying "enough, let's stop here." It usually carries a sense of being thorough, fair, and relatively decent.

For example, in the crypto market, sometimes investors tinker with a certain coin for a while and finally decide to withdraw. If you say "I'm calling it quits on this token," it means "I've decided to pull out of this token" — expressing both resolve and implying it's a rational, well-thought-out decision.

Conversely, if there's no longer mutual understanding about a market or project, maybe it's really time to call it quits. This phrase is common in business, investing, and personal relationships, and it's worth mastering.
