The "silly princess" sent by Nanchu to marry her, snatched the emperor's royal meal on the first day she entered the palace, hugged the legs of Beishuo Emperor Xiao Jinyuan and called "Uncle Bearded".
Everyone in the court laughed at her stupidity, but Xiao Jinyuan squinted in the dark - when this girl fell into the mud, the calmness in her eyes was not what a fool should have.
He deliberately threw her into the whirlpool of the struggle between powerful officials to see how she would muddy the waters with "silly words": when the imperial concubine made things difficult, she giggled, "The hairpin on my sister's head will bite"; when the prime minister framed her, she dragged the prince and shouted, "Grandpa has hidden a lot of knives."
Until she took off her disguise in front of him for the first time in order to save her father's old subordinates, her eyes red with tears: "Xiao Jinyuan, are you a fool?"
He grabbed her chin and said with a hot tone: "Really, you will know if you try it."
From testing each other to working together to clear up the traitor, when she used "silly words" to expose the prime minister's crime of collaborating with the enemy in public, he raised his sword to protect her in the Golden Palace: "My queen, even if she is 'stupid', it is not the turn of others to comment."
Later she understood that he pretended to be a coward in order to eliminate powerful ministers, and that he protected her not because she was a princess, but because she was Chu Nianqing.
