Su Yao is twenty-six years old and works as a copywriter and planner in Shanghai. Her life is routine and there is nothing worth talking about.
Until she had a dream. In the dream, someone called her name, and there was a road to walk and a door to open. She thought she was just too tired, but the things that appeared in her dream - a piece of jade with her name engraved on it, a bronze lamp, a bronze mirror hiding another face on one side - began to appear in reality one by one, each one after her dream.
She followed the clues into the Qinling Mountains and found the handwriting left by her grandfather and great-grandfather. She discovered that the starting point of this road was long before she was born - her great-grandfather brought out a silk book from a Han tomb in 1963. Her grandfather spent his whole life tracing the path recorded in the silk book, but they never finished it. The journey has reached her and continues.
In the dream, there was a platform with a lamp on it. When the lamp was on, the road would appear. When she walked to the fourth platform step by step, she saw a roll of paper, which said that someone had stopped here. She realized that this road was not meant to be walked, but to be walked through. Walking through means walking to the place where you decide to stop and still be whole.
She didn't make it to the finish line. She just got to where she was willing to stop. But the road itself was already in her body. She returned to the city with the lamp and the bronze mirror and continued her daily life, while the extra mole on her left eyebrow was still getting darker, waiting for her next departure.
