Don't do mindless time travel, and refuse to simply "crush everything with your golden finger". The protagonist holds the historical perspective of later generations, but is heavily constrained by the etiquette of the times, family status, party strife, and real financial resources. Instead of directly overthrowing the Song Dynasty, we tried to repair the three redundant diseases; we did not pursue temporary quick success, but paid attention to dormancy, games, and taking advantage of the situation; we took into account the ambitions of family and country, family ties, and close friends; we faced the reality of the Northern Song Dynasty: barriers between scholars, peasants, and commerce, hidden rules of the imperial examination, crony politics, the Three Kingdoms Game between Song, Liao, and Xia, land annexation, redundant troops, redundant officials, and financial crises.
