《三十年后》是山人乐队第三张专辑的首支单曲，宣告着山人的正式回归。作为《三十年》故事性的延续，《三十年后》在字里行间与器乐编排中，折射着时代的现状与自我的变迁。

葫芦笙、三弦、达比亚交织的傈僳族欢乐民间曲调下，唱起的却是房子、票子、孩子这些现代生活“老大难”。广播中激昂的宣传口号，掺杂着老乡们看热闹式的嘲弄，融于电气化的迷幻合成器回响。一幅充满魔幻现实主义色彩的山寨生活蒙太奇，在各种反差之间铺展开来，将现实的荒诞，反复无常展露无遗。

"Thirty Years Later" is the first single of Shanren’s third album, officially announcing the return of them. As a continuation of the story of "Thirty Years", "Thirty Years Later" reflects the current times and the changes of themselves, which reflects in their music.

Under the joyful rural tunes of the Lisu minority people who play HULUSHENG (A Single Spring Gasming Instrument), SAN XIAN (A Chinese Traditional Plucked Instrument) and DABIYA (A Chinese Ancient Plucked Instrument) , they sing the BUY A HOUSE, MAKE MONEY and RAISE CHILDREN, the difficult problems of daily life. The slogan in the broadcast is mixed with people’s ridicule melt in the echo of the electrified psychedelic synthesizer. A montage of cottage life full of magical realism, spread out between various contrasts, revealing the absurdity of reality and capriciousness.
