Liu Qingyue learned the wisdom of housekeeping from her aunt since she was a child. She originally thought she would marry as a concubine, but unexpectedly on her wedding night, she found that she had become the concubine's wife. The backyard is empty, and there is nowhere to put the skills I have learned to use. Just when she was confused, the cold-faced husband Gu Hanchuan asked her to teach her how to deal with it. It turns out that when Gu Hanchuan first entered the court, he was restrained everywhere and hoped to learn how to deal with it. Liu Qingyue will teach her the wisdom of retreating to advance and making good use of people's hearts, helping her husband grow from an ignorant newcomer to a capable minister who is highly valued by the emperor. The couple works hand in hand to write a legend together.
