In Europe, if a man still looked in his twenties when his wife died of old age, then he would be accused of deviltry and attacked by a mob whereas, in China, if a man remained youthful in appearance after many decades, then he would be regarded as a master of the Tao and invited to advise the Emperor! Poul Anderson shows us both of these outcomes in The Boat Of A Million Years. Neither of these deductions is correct but the Chinese inference is less harmful to say the least.
In Anderson's Rogue Sword, a man who has returned to Europe from China has become familiar with the idea that there is more than one way to God. Also, he knows that a Western Christian can accuse his neighbor of Devil-worship, then plant evidence, whereas the Chinese know how to protect a crime scene.
Thus, in two novels, we get the impression that the ancient Chinese civilization was more civilized than Western Christendom.
