Going to do something with 去 (qu)

Core idea

去 can come before another verb to mean going somewhere in order to do that action. The second verb tells the purpose of going.

This is a simple serial-verb shape. One subject does both actions, first going, then doing the main activity.

Usage boundary

Use this when actual movement is part of the meaning. If you only mean a future plan without movement, another time word or modal may be enough.

The action after 去 stays in normal verb-object order.
