Happy Birthday Vince,
I have flown domestic with Shenzhen Air & Hainan Air. Both did not have smoking allowed and boarding security was similar to domestic here in Canada. I do now that they are less demanding for requiring to remove footwear but you still need to empty your pockets and place laptops in the bins. For my personnel toiletries I think it a little humours that I have seen them opening my cologne and giving it a sniff.
