What is the ideological content of the lyrics?

Literal meaning:

As the sun goes down and night falls, listening to the music of bamboo branches in the south of the Yangtze River, I feel that people in the south only care about having fun and don’t know the suffering and sorrow of the people in the north! I have been singing this new song since the cold winter when the sky is full of snowflakes, and I have been singing it until late spring, when all the flowers have bloomed and withered.

*** Four of the lyrics of Ta,

According to the "Place of King Xiang's Forbidden City", this set of lyrics was probably written during the reign of Kuizhou , written about the folk customs in the Sichuan and River areas. The poet imitates local folk love songs and sings about the expectation and pursuit of love in a female tone. Of course, real life does not have such a rich and beautiful poetic flavor, but the hope, confusion and sentimentality for beautiful love expressed in the poem truly reflect the love for beauty that all human beings have and can never be wiped out. "The Continuation of a Brief Introduction to Poetry" says: "Every time I step on the lyrics, I will think of many beauties and herbs."
