Priority Pass (dlu1, checked 23 September 2026) places Best Business VIP Lounge before security and before passport control, from two hours before the first flight until the last flight. Maximum stay is two hours. Children under 2 are free. No smoking and no dress code. Facilities listed are air conditioning, flight information, and soft drinks. Wi-Fi is paid. The guest line that says unlimited is vague enough that it should be confirmed in the app. DragonPass's Dali page (DLU/l160) uses the same Best reception rather than a separate published A-code: turn left from the terminal doors, show the pass at the Best desk, and staff point you to the DragonPass room. Showers are not listed on either page. China Southern's airport blurb mentions a domestic two-cabin room on level 1, but that room is not this lounge and has no current public access page.
