Southerners never as good as northerners. I think it's because of the climate. Hot weather makes hard to fight and think. Land too fertile make people lazy. So southerners don't advance or progress, only get invade and conquer by northern peoples.
Your reasoning is flawed. The Arabs live in one of the hottest places on earth and they were able to conquer other nations and people. At their peak, the Arabs were more advance than the Europeans.
Who you think introduced
Algebra to West? It was the Arabs. Look at the Arab influence in places like India. One the great wonders of the world-the Taj Mahal is highly influenced by the Arabs. Anyway, enough with the Arabs. Hot weather doesn't mean shiit.
What gave the Northern Chinese advantage and made them such a dominate force over all of "China" IMO was due the fact they were more or less United than other groups at the time.
From what I understand, Lao/Dai/Tai/Zhuang were never a United people until later in the 7th or 8th century. As history is proof that once our people united we were able to expand and carved out our own territory(or in a modern sense "country").
