Searching for Southern Branches on the Moon

They shouldn't have crossed paths. One is the little maidservant of the girl in the boudoir of the back house, and the other is the counselor of the current prince and a distinguished guest of the Tian family. One only wants to be wise and protect himself, but the other is trying to figure everything out in the whirlpool of power, walking in the shadow of swords and lights. People who meet at night should never see each other again under the sun. The entanglement and entanglement end in farewell. . From the south of the Yangtze River to the north of Saibei, from the back house to the court hall, wherever we meet, we are separated, and we don't have to fall in love to miss each other. Mountains and rivers, the country, children's love, people's plans, love and hate.
