If you want to go further, it sometimes feels like the "who what where" pronouns are like sql prepared statements.

In English, we have question and answer

Q: Where do you want to go for lunch?

A: I want to go to that pub for lunch.

In Chinese you'd say

Q: You want to go to ?? pub for lunch?

A: I want to go to that pub for lunch.

It even works for numbers, like

Q: It is ?? o'clock?

A: It is 7 o'clock.
