鞋纸虽美但不合脚
[xié zhĭ suī mĕi dàn bù hé jiăo]
This name expresses the idea that while something might appear attractive or appealing on the surface (as 'pretty shoes' or 'nice shoes'), it is not right or fitting for oneself. The idiom reflects a philosophy of not pursuing things that don't fit one's needs, despite their charm.
