Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
chang soon » chang won, chin soon, chang gordon
can chang » can change, han chang, chin chang
soon hong » soon heng, boon chong, soon siong
yan guan » gan guan, yan yuan, yihan guan
tuan hua » tuan vu, yuan hui
wan yan » wang yan, nan yan, wai yan
tan hua » wang hua, tan chia, tan puay
hong yu » wong yue

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: wan yan ((((((yan guan) OR (yang guang))) OR (tuan hua))) OR (tan hua)) can chang soon hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((((yan guan) OR (yang guang))) or (tuan hua))) or (tan hua)) can chang soon hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((((((yan guan) OR (yang guang))) or (tuan hua))) or (tan hua)) can chang soon hong yu ;*.
