When the Han Family unified Zhongzhou, although they accomplished the grand feat of standardizing the tracks, scripts, and measures, humanity's ability to seek uniqueness always triumphed over the vision of unity.
Thus, there were dialects, there were colloquialisms, and there were distinct local cultures; some people were even too proud to use the script that had been passed down for a thousand years, opting instead for a different typeface.
Even some ancient families possessed their own clan language, which was only circulated and understood among their kin.

Some clans even took pride in these changes, feeling that their uniqueness was a badge of honor. So when the crew of the Wancheng Treasure Ship butchered without a hint of conscience, their hearts bore no pressure.
