"A tray of loose sand" literally means "a tray of scattered sand," and it is a metaphor for a lack of cohesion among the members of a group or organization, with each going their own way and failing to unite, like scattered grains of sand that cannot be gathered into a solid whole. This idiom comes from the Zhan Guo Ce, where the original text used "scattered sand" to describe a dispirited populace that was difficult to bring together. In its deeper meaning, it emphasizes not only numerical dispersion but also a lack of unity in spirit and action, which prevents the overall strength from being brought into play. It is mostly used in scenarios criticizing a team, collective, country, or society for lacking unity and cooperation, for being divided in spirit, and for being lax in discipline. Its emotional tone is generally derogatory, often carrying a sense of regret, criticism, or warning. In terms of cultural background, traditional Chinese culture emphasizes "harmony" and "unity," so "a tray of loose sand" is often used to contrast with the importance of solidarity, reminding people that only by building consensus and making concerted efforts can powerful strength be formed.
