This article takes Xiangchu's work on Ren Erbei's Dunhuang Lyrics Editor-in-Chief as an example to demonstrate and explain the development of Xiangchu's research practice and methodology of forming, learning and analyzing problems. This is the inheritance from those scholars between late Ming to early Qing dynasty. The uniqueness of this research method is to obtain knowledge from accumulating questions from solid daily reading and forming their perspective by solving these questions, which is quite different from the scholars who plainly accept the Western papers' writing standard, mimicking vague ideas from others and write the utilitarian papers for simple point counting. It is surely irrefutable that this is the only way to lead a successful academic research of having sustainable impact.
