Beauty research and development expert Song Qingyun transformed into a rouge craftswoman from the Song Dynasty. At the beginning, phenolphthalein was used to make the "Phoenix Kiss" lipstick that never fades, white vinegar was purified to make "Fairy Skin Powder", and zinc oxide was used to make "Wujinshuang". The noble ladies from Bianjing are crazy about it: "Produced by Qingyun Pavilion, it must be a high-quality product!" When I launched the "Charming Express" service, I bumped into Prince Lin Qi in the escort agency. He waved the folding fan: "I am interested in your brain, how about cooperation?" The county magistrate and my opponent teamed up to frame me for selling poisonous rouge. In court, I demonstrated acid-base neutralization in public: "Sir, this is called evidence!" On the way to escort the goods, bandits raided me, so I lit a homemade smoke bomb. When the imperial guards descended from the sky, Lin Qi chuckled in the smoke: "How dare you touch this lonely person?" He opened the window late at night and threw a bloody memorial: "There is a shortage of food in the north. Does my beloved concubine have any good ideas?" Later, during his coronation ceremony, the sunscreen under my phoenix crown glistened. The new emperor leaned over and whispered: "Queen, the color of your lipstick is very beautiful today, but is it the new phenolphthalein red?"
