"Is anyone home?"
Du Heng stood at the door of a house and shouted loudly, but there was no response from inside except for the WOOF WOOF WOOF of a dog.
The door of this house was made of wood, with a fist-sized hole in it.
Through this hole, he could roughly see the situation inside.
Hearing the dog barking in the yard and noticing no lock on the door, Du Heng shouted again, "Is anyone there?" He then walked over and knocked forcefully on the door a few times, trying to alert the people inside that he was looking for them.
Still hearing no movement, Du Heng bent down, intending to peek through the hole in the door. Just as he did, a dog's muzzle thrust out from the inside.
Du Heng nearly had an intimate encounter with the dog's nose, which frightened him into retreating several steps.
