Canonical page: 張軒睿 (Billy Chang).
Former provisional slug: billy-chang. Deeper material belongs on the canonical page; redirect stubs are not deepened (SKIP: no absorbable content on redirect).
Corpus re-grep 2026-10-01 (DEEPEN-X09261419-23): SKIP — no absorbable material on this slug. The two “Billy Chang” corpus hits are different people: 張宣信 (Billy Chang), the ITPC pastor (Who’s Who #2322, #910 Carnegie, and the 2022/05/15 槍擊案 memoirs — all already absorbed there), and 陳其明 / Qi-Ming Chang, Ph.D. ([[sources/taiwancenter-org|Taiwan Center Who’s Who #1273]]), whom the Taiwan Center board page also lists as Billy Chang. HOLD: two distinct people share the English name Billy Chang; do not merge either into this slug. Redirect stubs are not deepened.
