East wind means spring, so 3, 4, 5.
"Last night, the east wind entered Wuyang, and the flowers were bright." From Li Bai's "Seeing Your Majesty off in Hanyang in Early Spring". Last night, the east wind blew into Jiangxia, and the willows in the street had grown golden buds. Li Bai, whose word is Taibai, also known as "Violet Lay Man" and "Immortal", was a great romantic poet in the Tang Dynasty, and was praised as "Poet Fairy" by later generations, and was also called "Da Du Li" with Du Fu.
