My girlfriend gave me half a pear when we broke up. What do you mean?

The homonym of pear is "separation", and cutting the pear in half means "separation", so when you break up, your girlfriend gives you a pear cut in half to tell you that she is going to separate from you, so make a clean break and never contact again.

Therefore, in the traditional customs of some places in China, pears can only be eaten by one person, and cannot be shared among close people, for fear of bringing bad omen. Between male and female friends, sending each other half a pear when breaking up should be regarded as a parting ceremony.
