Perhaps you should try some spelling variations:
ylang yang » ylang ylang, wang yang, huang yang
wang liang » wang yang
yang yang » wang yang
dang thi » dang hai
thi cong » thi hong, thi mong, li cong
le dang » le sang, le duong
xi hua » xie hua, li hua
hua le » phua lye

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((ylang yang) OR (yang yang))) or (((wang yan) or (wang liang)))) xi hua le dang thi cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((ylang yang) OR (yang yang))) OR (((wang yan) OR (wang liang)))) xi hua le dang thi cong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ylang yang) OR (yang yang))) or (((wang yan) or (wang liang)))) xi hua le dang thi cong shu ;*".
