In other words—
When these common people, usually at the lowest rung, break free, the oppression naturally rises upward, especially as war commences, the overall trade regulation by Great Song naturally becomes weaker.
And as the war drags on, this matter will be infinitely magnified.
In the face of such a situation.
The authorities will only naturally choose to continue relaxing regulations, exchanging interests for more support to serve as military funds.
This is a vicious cycle.
Thankfully, maritime affairs haven't been too affected, given the Gu Clan's overarching control, an existence unshakable by others, as long as Ryukyu and the Malay Archipelago remain under the Gu Clan's banner, no one can sway them.
This, in many instances, alleviated the overall decline of Great Song.
Yet, weak is indeed weak.
