Seek all kinds of classics (at least Mozi, Mencius and Zhuangzi).

According to your words, it should not be doing research. First of all, what you need is a new edition of hundred schools of thought Integration (or Twenty-two Schools and hundred schools of thought Integration). All I know is that there is a scanned version, which is ugly. Moreover, as a research, it is still necessary to have the convenience of papers. Of course, if you have access to editing software, you can also use it.

Mozi's words and thoughts are relatively simple, but the words are not complete enough, that is, they are not complete in the process of circulation.

Mencius' thought is profound and direct. Since the song dynasty, it has entered the Confucian classics and has been studied a lot. In recent years, the main breakthrough is to excavate a large number of bamboo and silk.

Zhuangzi seems simple, but its realm is ethereal, and we need to understand more than superficial semantics. Therefore, it was learned by later metaphysicians. Then it became a classic of Taoism. Of course, research and misinterpretation are more.

In addition, Laozi, one of the traditional sources of China characters, especially the unearthed bamboo slips and silk books, should be very accurate and can be used as an introduction.

Hundred schools of thought's research, first of all, is the arrangement of the text, that is, the deviation of the text itself you see should not be too far. Secondly, clarify the original meaning of the text, and remember that approachable people often use "scientific" grammar, precise philosophy and universal theory to "interpret" the original meaning of various schools that are completely westernized.

Reading requires literacy. In addition to the text, there are also Er Ya and Er Ya Yi Lin, dialects and Yang Xiong dialects, Shuo Wen Jie Zi and Shuo Wen Jie Zi Evaluation, all classics, sounds and meanings, and classic interpretations.

Finally, it is suggested to choose a son first and do some in-depth reading, and refer to the relevant history of thought, the history of Confucian classics and the literary theories studied by predecessors here.
