Perhaps you should try some spelling variations:
thuat bao » thuat bai, thuat giao, thuat do
nang xa » nang x, lang xa, nang ma
va cham » va tham
va chat » van chat, va phat, cao chat
truc va » thuc va, thuc vat, trung va
hanh tu » anh tu, danh tu
bao ky » cao ky, ban ky, bac ky
thiet » thieu

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat bao ky nang xa hoi. hieu ((va cham) OR (va chat)) ((duc va) or (truc va)) hanh tu va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat bao ky nang xa hoi. hieu ((va cham) OR (va chat)) ((duc va) OR (truc va)) hanh tu va thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat bao ky nang xa hoi. hieu ((va cham) OR (va chat)) ((duc va) or (truc va)) hanh tu va thiet".
• Adding a wildcard symbol may retrieve word variants: thuat bao ky nang xa hoi. hieu ((va cham) OR (va chat)) ((duc va) or (truc va)) hanh tu va thiet*.
