In Changganli, Jiankang, a lamp circulates for hundreds of years, illuminating the rise and fall of four dynasties.
The lamp maker Chen Deng was born in the third year of the Liu Song Dynasty and the Ming Dynasty. He lived for ninety-six years and witnessed the changes of Song, Qi, Liang and Chen. He uses a lamp as a matchmaker and his heart as a fire, keeping an everlasting lamp in troubled times and an obsession that refuses to dissipate.
Dynasties reincarnate, kingdoms change owners, and old friends are separated. Only the lights of Qinhuai remain bright in the cycle of time.
The lamp never goes out, people never leave, love continues, and debts are clear.
This is the story of a craftsman who uses his life as lamp oil to guard the last bit of light in the world in a cycle of troubled times.
