The meaning of this poem is: If feelings are as beautiful as black smoke and blue and white flowers, there is no need to be afraid of the fleeting youth. Here, "ink smoke" may refer to black marks, just like painting flowers on Tao Pi, while "blue and white" may refer to blue and white porcelain, a beautiful porcelain. The whole sentence expresses the treasure and pursuit of beautiful feelings, as well as the short-lived helplessness and emotion for youth.
