This sentence actually reflects the censure and supervision of the rulers in ancient society. Tang was a legendary emperor in ancient China and was regarded as the founder of Xia Dynasty. However, in ancient China, the power of rulers was often very concentrated, so it was difficult for people to directly express their dissatisfaction or doubts about the rulers.
This sentence may mean that some people bravely questioned or accused Tang Di, hoping that Tang Di could improve his governance and policies. This reflects some people's worries about the abuse of power in ancient society and their attempts to safeguard social fairness and justice through questioning and criticism.
Generally speaking, the meaning of this sentence is to remind people to be vigilant against the actions of rulers, not to obey blindly, but to have the courage to question, so as to promote better governance and policies. This also reflects the important ideas of supervision and power balance in ancient China culture.
