India's great Maurya and Mughal that you see on map started from the conquest and lasted till the death of Ashoka and Aurangzeb respectively. The conquest of Kalinga, which make the greatest span of Muaryan lasted a little more than 28 years. The Aurangzeb Mughal which added Decan lasted a little more than 26 years. For most period, the Mauryan and Mughal were reigning only along the Indus Ganges plains.
In addition, Indians added a lot of vassal states and more ridiculously tributary states, that is not directly administered by Mughal into the Mughal map. By such standards, Vietnam, Ryukyu and Korea, the closest China' tributaries could be added on China's map.
And how Mughal is Indian is questionable? The real founder of Mughals Babur was from Ferghana valley of Uzbekistan. Ferghana valley was longed a vassal of China's Han and Tang dynasty. I do not see why someone can be proud by being conquered by Turkic tribe.
All Indian empire are pathetically small. Indians brag hard on their map giving a impression of unity state. There is no such thing. India's "empire" are actually result of mobsters raiding land with very little administration instituted. China is different. All Chinese empires are characterize by the highly consummated and centralized civil service system. The land are garrisoned.
