How does Pa Chin use imagery in Family?

Example of Imagery:

"Gnawing his lips and clenching his fists, Cheuh-hui listened. He forgot about his own affairs. He could see the full, pretty face of his sister-in-law, Jui, and a coffin. Gradually the coffin became two, then three. The faces of three girls appeared—one full and pretty; one mournful and sad; the third innocent and lively. The faces multiplied. Four, five—he knew them all—more and more and more. . . .Suddenly they all disappeared, and he was confronted with only the tear-staned visage of his Big Brother."
