Shang-Chi: 21 WTF Moments
1. Post-Credits Scene: Xialing Takes Over The Ten Rings
A few minutes before the credits hit, it's explained that Xialing has gone back to Macau to tie up her late father's affairs, but the post-credits scene reveals that, in fact, she's effectively installed herself as the slick new leader of the Ten Rings, complete with Razor Fist in tow.
Considering that it was established much earlier in the film that Xialing started the Golden Daggers Club at just age 16 after being rejected by her father, it's plausible that she'd have the follow-through to take advantage of the power vacuum in light of her father's death.
It remains to be seen of course whether this actually means anything substantial in the MCU. A Disney+ Ten Rings series, perhaps?
