鹊桥难渡
[què qiáo nán dù]
Referencing the Chinese legend 'the Magpie Bridge' in 'the Weaver girl and the Cowherd,' this expression suggests something precious yet unattainable. As per mythology, once a year the weaver girl meets her separated lover over a bridge formed by magpies, emphasizing obstacles that challenge even true relationships or unrequited desires remaining out of reach despite sincere wishes or efforts to achieve them.
