What does Liu Bei mean by crossing the river?

Love each other. According to Netease News Network, Liu Bei crossed the river in the spring breeze to ask his wife to cross the river, so later generations used the word Liu Bei to describe the meaning of so-and-so love. Liu Bei, Emperor Zhaolie of Han Dynasty, was born in Zhuojun County (now Sangcun Village, Dashulou, Zhuozhou City, Hebei Province). Liu Sheng, who originated from Zhongshan King in the Western Han Dynasty, was the first emperor of Shu Han during the Three Kingdoms period.
