The fifth is 'the people.' What is meant by this? When a minister distributes public funds to please the populace, dispenses petty favors to win over the commoners, and makes the court and marketplace all eager to speak well of him, thereby obstructing the ruler and achieving his own aims -- this is called 'the people.'
The sixth is 'popular eloquence.' What is meant by this? A ruler by nature has restricted access to discussion and debate, rarely hears deliberative argument, and is easily swayed by persuasive speech. When a minister recruits eloquent rhetoricians from the feudal states and patronizes skilled debaters within the realm, deploying them to argue his private interests -- crafting clever formulations and flowing rhetoric, dangling prospects of advantage and power, threatening with dangers and harms, stringing together empty phrases to undermine the ruler -- this is called 'popular eloquence.'
The seventh is 'coercive force.' What is meant by this? A ruler of men derives his power and strength from his ministers and people. What the ministers and people approve, the ruler approves; what they do not approve, the ruler does not approve. When a minister assembles sword-bearing retainers and maintains men sworn to die for him, thereby making his power conspicuous -- making it clear that those who serve him will profit and those who do not will die, thereby intimidating ministers and commoners alike to carry out his private ends -- this is called 'coercive force.'
The eighth is 'the four directions.' What is meant by this? When a state is small, it must serve great states; when its army is weak, it must fear strong armies. What a great state demands, a small state must obey; what a strong army imposes, a weak army must submit to. When a minister levies heavy taxes, empties the treasury, and drains the state to serve a great power, then exploits that power's leverage to coerce and manipulate his own ruler -- at worst, massing troops on the borders while extorting compliance at home; at best, repeatedly introducing foreign ambassadors to intimidate the ruler into fear -- this is called 'the four directions.'
All these eight are the means by which ministers achieve treachery, and the means by which rulers of the age are obstructed, coerced, and stripped of what they possess. They must not go unexamined.
