Chronicles of Qinglan Mountain

In 2001, Qinglan Mountain Forest Farm was restructured, and twenty-four-year-old records clerk Shen Yan went up the mountain to complete the forest farm's chronicle.

He found a curved-handle saw in an abandoned sawmill. The moment he touched it, a snowy night appeared before his eyes: in 1983, lumberjack Liu Changshun died in the sawmill, and the farm office concluded that he had "frozen to death."

But the saw remembered that there had been a second person there that night.

Every time he touches an old object, his nose bleeds and he sees a fragment of someone else's memory. A saw, an enamel mug, a photograph of three people: pieced together, the fragments point to the old bookkeeper with the abacus at the supply and marketing cooperative down the mountain.

His father investigated for three years, then locked his notes in a drawer, leaving behind only one sentence: "Xiao Shan is still alive."

The mountain is to be turned into a scenic area, and one by one, people are leaving. Shen Yan has only forty days.

Before the bulldozers enter the mountain, he has to reopen a case from twenty years ago.
