This question can be clearly answered. Wang Mang is definitely not a traveler.

At present, what can prove that Wang Mang is a traveler is that his thoughts and ideas and many habits and hobbies seem out of place in ancient times, which is in line with modern standards, but this is definitely not a feature of crossing. What is the strongest advantage that the protagonist has when reading time travel novels? Many people will say that the protagonist has a lot of scientific and cultural knowledge in cash, but this is only the second. The greatest advantage of the protagonist is that he knows how the later history will develop. Clearly know those people are potential stocks and those people are mine stocks.

Among the cultural relics of Wang Mang's New Dynasty unearthed in modern times, there are vernier calipers with modern precise measurement and miniskirts for women now. For this matter, we can understand that among the ancients, there are always some people who suddenly opened their brains to some inventions, which is not surprising. The principle of vernier caliper is not complicated. To make this kind of thing, you don't need a lot of modern scientific and technological theoretical knowledge as a support, but the miniskirt is just a conceptual difference, and there is no technical content.

The same is true of Wang Mang's later "socialist system, running a university" in the new dynasty, which is only some innovation in concept, and there is no evidence to prove that it was brought from modern civilized society! If Wang Mang is really a traveler, then he should know more or less about the later history. There should be a lot of evidence to prove that he knew the later historical process, so he should leave a lot of predictions to warn future generations. From the current historical excavation, there is no evidence that Wang Mang knows what will happen later.

and for a person who opens up, he is certainly not so easy to fail, but in fact, in the year 23. Greenwood hero, an army invaded Chang 'an, and Du Wu, a businessman, killed Wang Mang.
