Depends on my mood.
This one is totally out of tune, but that's the way I like it

"I stiiiiiiill dreeeeeaaam ooof Decembeeeeer...
Dancing togeeetheeeeeer, wiiith riiings
on our fiiiingeeeeers........
And theeee twoooo shall beeecooooooome...
Beeeeecoooooooooome!!!.................."
This is another favorite, romantic but much much milder
"re sou sou xi dou xi la
RE SO SO TI DO TI LA
sou la xi xi xi xi la xi la sou
SO LA TI TI TI TI LA TI LA SO
chui zhe qian zou wang zhe tian kong
Playing a prelude, gazing into the sky
wo xiang qi hua ban shi zhe diao luo"
I think of petals about to fall
