The first sentence: "The word civil law has no roots in ancient books." It means that there is no standard classic or classic like Confucian classics to refer to when formulating civil law, so every period and place has its own derivatives and changes when formulating civil law. This also shows that China's civil law has been constantly developing and changing.
The second sentence: "The reform of the Qing Dynasty was copied from Japan." It means that reform and innovation were carried out in the late Qing Dynasty, and some reform measures copied Japanese experience, but these measures may not be suitable for China's national conditions and actual conditions. In a word, this sentence expresses some doubts and reflections on the formulation and reform of civil law.
