An elementary school student did not recognize the character "槐" (huái) and asked his older brother, who was in the first year of junior high school, for help.
"Brother, what is this character?"
"'Ghost' character."
"Do ghosts have a 'wood' radical?"
"It's the ghost that hangs from trees."
The same story repeats multiple times with different contexts but essentially conveys the same humorous misunderstanding between the younger sibling and the older sibling about the Chinese character for "槐" (huái), which refers to a type of tree but humorously misinterpreted as a "tree ghost."
