Yes, it would be really funny if Singapore can somehow wrestle out
of China and regain independence again after being swallowed by
China.
How would you imagined that to be possible?
I would like to hear about it cos it would be really funny.
You may add your Transformers, Harry Potter, Gundams, Pokemons,
and plenty of other characters to make it happen.
But then again, if even you can't make it up in your
imagination. Then it's not going to happen.
Hmm....wait.....Is your post meant to be funny in the first
place? 
Hey .. the topic of Singapore going to be part of china is not
possible in the first place . There is no link between this 2
countries at the start unless you live in the times where china
thinks they own the world.
Singapore got a track record of achieving independence. Why
going with the odds , my say of singapore achieving indepence far
out weights your acceptance of china swallowing singapore up .
