This sentence came from the Tang Dynasty poet Liu Yuxi's "Humble Room Inscription". The whole sentence was: "If the east wind does not give Xilang, then the bronze sparrow will lock up the two Qiao in the deep spring." This poem described Liu Yuxi's simple home and the beauty of the surrounding scenery, expressing his worries about the current situation and his pursuit of beautiful things. The phrase "the east wind doesn't give Xilang a chance" referred to the great difference between the seasons in southern and northern China during the Tang Dynasty. Spring and autumn were different, so the poet lamented the change of nature and its difficulty in control. And "Copper Sparrow Spring Lock Er Qiao" referred to the two noble women of the Tang Dynasty, Er Qiao. Qiao and Xiao Qiao were locked together by their master Cao Cao to show Cao Cao's cruelty and possessiveness.
