Does the judge have the right to refuse the trial?

It is a principle of a society ruled by law that a judge cannot refuse a judgment because there is no explicit provision in the law. But for some reason, my ears are full of such information. When citizens' rights and interests are infringed, the court will refuse to accept them for various reasons. Theoretically, the court funds ultimately come from taxpayers, and citizens pay taxes as taxpayers, that is, they buy services, so the court has no reason not to accept them. The state monopolized the way of judicial relief by setting up courts. If a citizen has a dispute and the court refuses to accept it, who can the citizen turn to? Perhaps, the provisions of Article 4 of the French Civil Code are of great value to the settlement of disputes between the owners of Taiping Homeland and property management companies in China: if a judge refuses to make a judgment on the pretext that the law is not stipulated, the provisions are unclear or incomplete, he may refuse to pursue the trial.
