Wooing refers to gaining trust and attention through words and actions. This phrase comes from Hu Yinglin's Poems under the Ancient Style in the Ming Dynasty: "Violet's Yi Dao Qu ... is clear in context and fluent in sentences, so it is self-contained and then acquired."
Be happy, which means happy and like it.
Generally speaking, spiritual or material efforts (such as words and actions) are used to gain someone's love or attention and achieve their own goals, which can be positive or negative.
