Why did Danny have to clarify in advance to Gao Guang that Eric was a redneck? Because if he didn't make that clear beforehand, Gao Guang would certainly think that this seemingly ordinary old man in front of him was just a plain old man.
Decked out in a plaid shirt, with a pair of jeans underneath, and tall boots on his feet—not the trendy kind, just a very common pair of tall Texas boots. Fortunately, he didn't go so far as to wear a cowboy hat, but he did sport a baseball cap.
That's the clothing. As for his appearance, a round and chubby old man with a small beard on his chin, his face sunburned red. He neither looked fierce nor serious, just a very typical Texan farmer. Walking down the street, you'd see about one-third of the men driving beat-up pickups looking like him.
If Danny hadn't told him in advance, Gao Guang would really believe this old man was just an ordinary farmer.
