One deep winter, Luo Yicheng had a daughter Luo Xiaobei. Because Luo Yicheng's wife, Zhang Yin, had no milk, the child cried all day. He Ping learned a remedy from his wife, Tang Lihua, so he asked Luo Yicheng to go to the river to break the ice and fish on weekends to prepare Zhang Yin's milk. Luo Yicheng accidentally fell into the water, He Ping jumped into the ice hole and pushed Luo Yicheng up. Unexpectedly, He Ping drowned. On the same day, Tang Lihua, who was suddenly hit by her husband's death, gave birth to her son He Chunsheng. This strong woman is very brave. Hearing the cry of the daughter next door, she came to hold the child in her arms and breast-fed her with her own milk. He Pingfei died in the line of duty, and his superiors refused to report the martyrs. Luo Yicheng jumped up and down in vain, self-reproached, determined to take good care of the life of the widow and mother of CSI no matter what, stick to the promise of chatting with CSI on the ice, and let the new men and women get married. He asked two mothers to hold their newborn children and took an "engagement photo".
