Perhaps you should try some spelling variations:
van chat » cao chat
danh dai » danh dau, danh di, danh sai
thuc va » thuc vat, thuc dan, thuc day
truc va » thuc vat, trung va
su viet » so viet
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
dai su » dai sua, dai so, dan su
te sac » te sach, te cac, te san

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang xa hoi. hieu ((va cam) or (van chat)) ((truc va) OR (thuc va)) danh dai su viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ((va cam) OR (van chat)) ((truc va) OR (thuc va)) danh dai su viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ((va cam) or (van chat)) ((truc va) OR (thuc va)) danh dai su viet*".
