IIT residence is domicile or meeting the day-count test — it is not ‘I have a Z-visa’ and not automatically worldwide tax forever.
PRC Individual Income Tax residence depends on domicile in China or presence meeting statutory day-count rules. Residents and non-residents face different worldwide vs China-source scopes. The live 183-day basics wiki and foreigner 183-day guide already own day-count narrative depth — this page is the atomic residence definition for the expansion map. The six-year rule is the anti-worldwide-reset related pages. Departure clearance is a different exit file. Do not invent a second 183-day related guide slug.
