There are right and wrong ideas, how to distinguish them?

What concept? Ideas are the subjective reflection of objective things. Thought originates from things and describes things, and things are independent of thoughts.

Ideas are human cognitive tools, not the ultimate goal. We know the world through various concepts, deepen our understanding of the world, and thus better transform the world.

Test the right and wrong of ideas in practice. The correct concept faithfully reflects the original appearance of its object, while the wrong concept is a distorted expression of the objective world. The more you touch something, the deeper you understand it and the clearer your thinking.
