袖竹空羡
[xiù zhú kōng xiàn]
This refers to envying others' relationships while feeling empty or powerless about one's own inability to have similar success in romance. The character 竹 (bamboo) here symbolically means something elegant but unattainable, as bamboos sway gracefully with the breeze, evoking envy but remain untouched just like the aspirations of the individual using this username.
