There was a famine in Qinghe Village. Zhang Xiaohe saved his family with a bowl of grass root porridge, but was chosen by the draft official and sent to the palace. Just because she refused to cling to the powerful, she was relegated to the cold palace and became a useless concubine. My childhood sweetheart's fiancé regretted his marriage overnight, and the palace officials and eunuchs made every possible effort to make things difficult. The cold palace is a forgotten wasteland - the walls are crumbling and the ground is cracked, rats and ants are rampant, and clean water is hard to find. But Zhang Xiaohe is not afraid. She remembered the ancient saying from the wasteland passed down by her grandma: "Mother of the Earth repays, cherish blessings and gain blessings." She was blessed with the luck of koi carp, but found that good luck did not come out of thin air: for every person who joined, the luck would increase by one point; for every grain of rice wasted, bad luck would catch up with them. She gave a bowl of wild vegetable porridge to the old nanny in the cold palace, then turned around and dug out half a can of old rice seeds under the broken wall. She taught the little eunuch how to grow sweet potatoes, and the next day a hare knocked on the door. The cold palace gradually came to life - the corners were covered with beans, loaches were raised in the broken tank, and even the rotten vegetable leaves discarded in the imperial kitchen were pickled by her into appetizers. People from all directions began to flock to the cold palace: bullied palace maids, disabled veterans, orphans fleeing famine... Zhang Xiaohe accepted all comers, and her restaurant opened from a broken pot, and the fragrance spread for ten miles. But the Cold Palace is a place outside the law after all. Once the former harem is alerted, everyone will be executed. When the empress's phoenix chariot stopped at the entrance of the Cold Palace, and when the regretful fiancé knelt in the mud and begged her for forgiveness, Zhang Xiaohe just lowered his head and scooped out a bowl of porridge: "My guest, a bowl of ten taels, I refuse to bargain."
