元好问 was 16 and travelling to the exams in 1205 when a hunter told him a wild goose had dashed itself to death after he caught and killed its mate. Yuan bought both birds, buried them and called the grave
雁丘 'Goose Mound'. The poem's line
直教生死相许 'that it makes two pledge each other life and death' is still quoted of devoted love.
