No.
You can EXIT at Luohu on a Guangdong 144-hour TWOV (assuming you somehow meet the ticket-out requirement), but you can't even exit at W Kowloon.
Ok, thank you. What about a 24 hour one? Sorry, I didn't specify, but that's what I meant. If still no, why? The rules technically say I could enter by any means and must leave by air
