头发太长会开叉
[tóu fā tài zhăng huì kāi chā]
Translating to 'Hair too long will split,' this nickname can imply a person who has learned a lesson from experience - like that overly long hair might need extra care to avoid splitting ends. Metaphorically, it could refer to the consequences of overdoing something or not paying enough attention to one's appearance or well-being.
