Perhaps you should try some spelling variations:
parents does » parents roles, parents dans, parents do
hua parents » his parents, aux parents, h's parents
long chain » long chemin, long grain, long han
wang yang » wang yanling
does plan » does place, does plate, does land
plan long » place long, plan loans, pain long
nan hua » tan hua, wang hua, tuan hua

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang liang) OR (wang yang))) or (wang yan)) nan hua parents does plan long chain ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang liang) OR (wang yang))) OR (wang yan)) nan hua parents does plan long chain ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang liang) OR (wang yang))) or (wang yan)) nan hua parents does plan long chain ;*".
