I'd get one just in case even if they're among the sickest jokes the United Kingdom has ever played on its subjects. And that's saying something. We'd have to go back to WWII India or even the East India Company to find something sicker and more selfish.
In the worst case it's just a sad relic to pass on to your offspring (if any) and a crime in the P.R.C. As far as expectiations come, that's par for the course for the average Hongkonger so what's there to lose?
Boris is just a navel-gazing male bimbo so showing him some Hongkonger babies (actual infants ffs, he doesn't need any tempting) in distress might seal the deal as long as he's in office and there's any residual 'postpartum' oxytocin left in his sorry torso.
