Read this passage from Dragonwings by Laurence Yep.

"Whoa, Red Rabbit." Father pulled at the reins and Red Rabbit stopped. Father set the brake, and as an extra precaution he put the wooden block behind the wheel.

"Can I help?" he asked.

The demon was a big, cheerful-looking demon with a bland, round face. He eyed father. "I dunno, John." Many demons called Tang men John because, they insisted, they never could get the hang of our real names. "You know anything about horselesses?"

Which detail shows that white people and Chinese people struggled with interacting with each other in the early 1900s?

The father stops to help the stranded man.
The man is cheerful-looking.
The man calls the father John.
There is a horseless carriage.
