Dial the horse's head to tell fortune.

A word from Ba: When they saw us, the master immediately turned his horse's head.

The original sentence is from Grassland, written by Lao She.

This is the host welcoming the guests from afar dozens of miles away. When the master saw us, he immediately turned his horse's head, cheered and ran to lead the way in front of the car. The quiet grassland became lively: cheers, cars and hooves rang together. The car followed the horse over the mountain and saw some yurts.
