A key advantage of the aerosolized version of the CanSino vaccine is it's lower dosage, around 1/5 of the injection version, which means 5 times more booster shots.
Phase III results for Taiwan’s Medigen vaccine.
It’s difficult to compare data from different studies, but Medigen seems to result in slightly weaker immunogenicity than Clover’s candidate. Medigen and Clover use the same adjuvant, but Medigen uses US NIH’s S-2P platform for antigen (same as the one used for Moderna) whereas Clover uses its proprietary Trimer-Tag platform. It’d be interesting to see if the Trimer-Tag platform can be used for mRNA vaccines. Walvax’s mRNA candidate uses RBD rather than S protein.

I do not agree. The reason is that your choice impacts me more than my choice impacts you. Our choices do not have nearly equal impacts, so we do not deserve equal freedom to choose one or the other.
The reason of course is that the virus is contagious. Opening up (your choice) increases my chance of dying. Your "freedom" comes at my expense, and I object to that. My choice (of zero Covid) is morally superior, as it does not increase your risk of death from the virus.
The Zero Covid strategy may even be superior economically. China is actually growing faster than it was doing before the pandemic; the extra growth is probably at the expense of those countries who bungled their Covid policies. By opening up, Singapore could become another of these losers.
So the Zero Covid strategy is superior morally and economically. If your choice of opening up affected only you, perhaps I'd grant you the freedom to choose that path. But it affects more than yourself, so I disagree that it's an issue of "to each his own".
That is why drinking alcohol is heavily regulated in most countries; so is smoking, but less so. Covid needs to be attacked at least as ferociously as drinking -- not in the same way, as the virus doesn't understand regulations, but at least as strongly.
Perhaps some day an effective cure for Covid-19 will emerge. Until such a cure exists and proves to work, I see no reason -- not even economic reason -- to abandon the Zero Covid strategy.

China's Zero-Covid strategy is a "candle strategy", lighting others, burning one's own. At this stage, it is very hard to ask others to follow your choice. So, if you feel their choices impact you more then block them from entering your country. Period!
Inhaled vax typically don't work well compared to injected vax. FluMist does not work as well as injected vax. NasoVax does not work as well as injected vax. CanSino is not an effective vax to begin with, only 65%. It would never be approved in the west.

It would never be approved in the West even if it had 100% effectiveness.
That's right. Because China blocked CanSino shot to Canada and humiliated Canada because of Meng Wan Zhou. Payback time.
