Chú *Trang Tử* (Nam Hoa) của Lục Tây Tinh, xem *Nam Hoa* như chú sớ của *Đạo Đức Kinh*, lấy ‘thường vô hữu’ và ‘xuất vi ư bất vi’ phá chấp. Tiêu Thiên Thạch coi đây là đỉnh Trang học Kim–Nguyên–Minh. Tàng ngoại; khác hẳn *Đạo Đức chân kinh huyền lãm* (đã loại) dù cùng tác giả.
Ứng dụng: Đọc song song với *Đạo Đức Kinh* khi cần Trang học nội đan–nghĩa lý đời Minh.
Lu Xixing’s argument is that Zhuangzi’s free wandering is not aesthetic relativism but a rigorous unbinding of fixed cognitive axes so that the mind can rejoin the transformative continuum of qi. '副墨' (secondary ink) proves that written meaning is only a pointer; liberation occurs when the reader stops treating the pointer as the territory. The text thus converts literary paradox into a method for dissolving attachment to any single interpretive frame.
1) In BaZi counseling, refuse single-story destiny: show alternate useful framings of the same structure. 2) For stuck day-master identity, practice 'perspective inversion' (what if the weak is the path?). 3) In cultivation, alternate stillness and playful observation to prevent doctrine-hardening. 4) Use dream/image work as temporary pointers, then drop them. 5) Test progress by flexibility under luck-pillar change, not by fixed self-image stability alone.
Unlike 庄子集释’s philological polyphony, 副墨 is more neidan-adjacent and mind-training oriented. Unlike 道德经 commentaries that center non-action as governance logic, it centers transformational free-wandering as cognitive liberation—same Daoist family, different proof object.
