Still, of these Games, no advanced degree in international relations was required to appreciate the genuine warmth of the Chinese people, the honest pride in their country and how seriously Chinese citizens, famous Olympians, to everyday men and women, took this chance to show themselves to the world.
这句话no advanced degree怎么理解？后面句子怎么翻的通顺些？

不需刻意的国际关系，在这些运动项目中，世人依然能够欣赏到中国人真挚的热情，中国著名奥运会运动员如何认真地展示自己的技艺。这已成为该国民众诚挚的骄傲。
no advanced degree的字面意思可以理解为‘没有任何超级的程度（地位）’，这是指国际上交往之间的关系程度，说明观众的心里偏爱趋向，没有什么超越的感情关系，只是在赛场上一种感觉。
