Perhaps you should try some spelling variations:
ylang yang » ylang ylang, yang yang, wang yang
yang liang » wang liang, yan liang, yang yang
john song » john ngosong
liang li » ling li, qiang li, liang wei
lu ying » li ying, lu ding, lu xing
ku ying » ka ying, ku ring, hui ying
bonn » bond, born, conn

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: ylang yang liang li ((lu ying) OR (ku ying)) ((((john wong) OR (john bonn))) OR (john song)) sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ylang yang liang li ((lu ying) OR (ku ying)) ((((john wong) or (john bonn))) or (john song)) sam ;~".
• Adding a wildcard symbol may retrieve word variants: ylang yang liang li ((lu ying) OR (ku ying)) ((((john wong) or (john bonn))) or (john song)) sam ;*.
