苏轼 wrote it in 1075 as prefect of
密州, in today's Shandong, after leading a hunt. It opens
老夫聊发少年狂, 'this old man, for once, lets loose a young man's wildness', though he was not yet forty, and ends with the wish to draw his bow and shoot the Wolf Star,
天狼, meaning the enemies on the northern frontier.
