The extra security for Wuxi was because you were heading to Shanghai and at the moment there is the China International Import Exhibition on now which is apparently a high security event because it is the brainchild of Xi DaDa.
No QR in our case--her sisters used their ID cards, we used our passports. No on-board seat checks at all. On the return trip my wife and I never even knew what our proper seats were, we simply took empty seats near her sisters, prepared to move if someone showed up wanting them.
