The disciples were absorbed in a discussion of Lao-tzu's dictum:

弟子在一次老子论断研讨会上全神领会：

Lao Tzu has no monograph on the concept of time, but Lao Tzu's philosophy includes his view on the Time, called Lao Tzu's Philosophy of Time.

老子没有论述时间的专著，但老子的哲学思想中包含了他的时间观，可称之为老子的时间哲学。

Taoism worships Lao Tzu, a pre-Qin Dynasty philosopher, as the founder.

道教奉先秦哲学家老子为道祖，以老子的《道德经》为基本经典。

That's what Lao Tzu means when he uses the word wu-wei.

那就是老子用“无为”这个词的含义。

On the other hand, greater importance is being attached to Lao-tzu itself and its Chinese background.

学术性不断增强，对《老子》本身越来越重视，对《老子》所在的中国文化背景亦有所关注。

Is it merely because he was born in the land where Lao-tzu once lived ?

难道仅仅只是因为他恰好生活在老子曾经生活过的那片热土吗？
