Mr. Jin took care of the son of a friend from his hometown, but the friend died unexpectedly. The boy became an orphan and was renamed Jin Chao. Three years later, his wife, Ms. Jiang, became pregnant and gave birth to a daughter, Jin Mu. The huge pressure of life made the conflict between the two people worse. When Jin Mu was 9 years old, her parents agreed to divorce, and she lived with Ms. Jiang in the south. Mr. Jin took Jin Chao to a small town in the north. From then on, the north and the south were separated and never contacted each other until they died. Until Mu Mu was 18 years old, Ms. Jiang followed her second husband to apply for immigration. She was temporarily sent to Jin's father and met Jin Chao again after nine years. *Morning is the sun, evening is the moon, the sun and the moon shine together, morning and evening.
