sorry man i'm not working on comparative history projects... yet. So far, I think most people understand that Chinese mainly focus on Chinese history which has also become full of Western revisionism. When you see such articles presenting evidence against the distortions, maybe it is government-linked, maybe it isn't, but remember that there are definitely patriotic (or sympathetic non-citizen) humanities majors working on it.
As for Romans and China, the comparison is like apples to oranges haha, the Romans were primarily a war machine, i.e. very high iron production, large standing armies, but fueled by distributing conquered farmlands to soldiers and selling captured slaves. And the early Empire (until 284AD) was governed jointly by the emperor and the Senate aristocrats, the former governing the outer provinces and the latter the inner provinces. The moment the empire could not find anymore easy conquests (Dacia, Germania and Parthia either being too united or too inaccessible) which you see happening around 180AD, the whole empire came crumbling (235AD) and the legions and the Senate began elevating their own emperors, with the last one standing getting to pillage the rest. Emperors destroyed the economy raising taxes and debasing the currency to pay off the army. After that date every emperor except Aurelian and Constantine had to divide the empire into parts for different emperors to rule, or face civil war.
Han China in contrast was a civil state that succeeded in creating a powerful central government. War with the Xiongnu, open steppe warfare, depended on horse not iron/manpower supply. It was only winnable through co-opting some of the horse tribes by providing generous financial and material benefits, while preventing the Chanyu from co-opting Han vassal kings to cut off his grain/silk supply. All these processes need political consolidation at a level unknown in Rome which never had a clear system of succession and heavily relied on the emperor's personal presence for many aspects of justice and warfare.
