Based on a large-scale corpus, an exhaustive survey on the formal verb "zuo(做)/zuo(作) " in Malaysian Huayu was conducted to validate the feasibility of a micro comparative study of Huayu vocabulary. Huayu research should strengthen the micro-studies of words and make words the most important research content, while "subordinate awareness" or "lower subordinate awareness" should be established to carry out "fine granularity" and "high definition" research of words. During the specific research, the following three points are of vital importance: first, from the corpus, and then to the corpus; second, detailed and sufficient observation; and third, multi-perspective examination, verification, and interpretation.
