Grandma asked Zhang Ga to do something in the village every day.

Grandma asked Zhang Gazi to go to the village every day, that is, to send some food to Uncle Lao Zhou and/or to see if the enemy was coming. Because soldier Zhang Ga is in the middle of the village, he is a soldier, the captain of Zhang Ga, and he is in charge of public security in the village, so he will go to see if any outsiders are enemies or sound out, so Zhang Gazi will go to the edge of the village to see if there are any enemies coming.
