huns, halaku and many turks were not muslims,
muslims invaded the eastern part of chinese region, as per my info the only muslim/turk ruler who ever decided to invade China was Taimor and he also died on his way to China, none other looked east.. they were more concentrated on India, Central Asia and Eastern Europe… anyway Chinese wall is their to protect them from the invaders.. it can be anyone…
Did i said that the both countries have bought it in one go… i am showing you the moon and you telling me that my finger is twisted.. no wonder we end up fighting
