Perhaps you should try some spelling variations:
main chance » main changes, main charge, chain change
main chang » main changes, main charge, chin chang
soon siong » boon siong, soon seng, soon soon
wang yang » wang yan, wang liang, wang yanling
done sin » dong sin, done using, done so
siong yu » hong yu, siong _, ming yu
ya a » a a, y a, ye a

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((done sin) OR (wang yang)) ya a ((main chang) OR (main chance)) soon siong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((done sin) or (wang yang)) ya a ((main chang) OR (main chance)) soon siong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((done sin) or (wang yang)) ya a ((main chang) OR (main chance)) soon siong yu ;*.
