There is a humorous joke. What hammer?

A father and son in Sichuan walked into the digital city.

My son went to the mobile phone monopoly and said to his father, Dad, buy me a mobile phone!

The shopping guide rushed over and said, sir, do you want to buy a mobile phone?

Father: No.

The son stubbornly tugged at his father's sleeve: Dad, buy me one!

Father was angry and scolded in Sichuan dialect: I'll buy you a hammer.

..... Father and son quarreled. ...

After a while, shopping guide: sir, the hammer mobile phone you want has been wrapped.
