Qiankun Wannian Ge (乾坤萬年歌)

The Ten-Thousand-Year Song attributed to Jiang Ziya (姜太公) — the OLDEST-attributed of China's great prophecy texts, and the fourth on the verbatim shelf beside the 推背圖, 馬前課 and 燒餅歌. One hundred and ten seven-character lines — exactly 770 characters, the very figure the popular literature publishes — walking the dynasties in riddles: 而今天下一統周 through 委鬼 (魏), 耳東 (陳), 木易 (楊隋), 木下男兒 (李唐), 一汴一杭 (宋), 十八孩兒 (明 — the same motif the 燒餅歌 carries), down to the sealing couplet 知音君子詳此數，今古存亡一貫通. FOUR LAWS asserted at load: the FORM law (110 lines, uniform 七言, 770 characters exactly), byte-exact RECONSTRUCTION (rolling checksum — one altered character refuses to boot), the opening/closing anchors, and the dynasty-riddle CHRONOLOGY law (the verbatim-datable tokens must appear in historical order). Query the whole song, one line, or any range. The variant popular recension (石上坐 for 石上生, a 106-句 segmentation of the same 770 characters) is NAMED and never blended; the attribution to Jiang Ziya is served as the legend scholarship considers it. A classical 讖緯 text for literary and historical study — NO claim any line predicts modern events.
