In recent years

the application scope of grounded theory research in the field of traditional Chinese medicine (TCM) has gradually expanded

and the various research needs such as "Dao and Shu(doctrines and techniques)" of illustrious senior TCM practitioners can be met. However

this research requires significant time and energy because of too much code

long study period and rework the meaning of code. Therefore

in this paper

on the premise of conforming to coding principles

we creatively propose a method named "cascaded coding" that uses Office Word to code the raw materials and then imports cascaded codes into Office Excel in order to clarify all categories and the concepts at all levels attached to them. Furthermore

mind-map software is used to visualize the cascaded codes. This cascaded process is discussed in this paper

and the grounded theory is taken as an example to analyze the Dao of an illustrious senior TCM practitioner-Prof. Kong Guangyi. Based on the methodology of grounded theory coding principles

we optimize the operation path and simplify the coding process

saving time

ensuring coding efficiency and accuracy

and providing an example for researchers who conduct grounded theory research on illustrious senior TCM practitioners

thus help more TCM qualitative researchers to carry out grounded theoretical research convenienty

accurately and at low cost.
