Perhaps you should try some spelling variations:
yang yang » wang yang
irene kan » irene a
tuan hua » tuan vu, yuan hui
min hong » amin hong, tin hong, min hyoung
hong shu » cong shu, tong shui, wong shiu
tan hua » wang hua, tan chia, tan puay
kan min » han min, kian ming, kyaw min

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: ((yang yang) OR (wang yan)) ((((tuan hua) OR (tan hua))) OR (yuan fei)) irene kan min hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (wang yan)) ((((tuan hua) OR (tan hua))) or (yuan fei)) irene kan min hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (wang yan)) ((((tuan hua) OR (tan hua))) or (yuan fei)) irene kan min hong shu ;*.
