Perhaps you should try some spelling variations:
va trien » va truyen, va thiet, va tuyen
ban hanh » ban hang
va thanh » gia thanh, ban thanh, va tinh
tu nang » tru nang, tu nong, tu nano
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cac xuc » cac nuoc, chat xuc, cac cuoc
so anh » so sanh, so danh, do anh
anh tu » anh tuan
vi va » vi van, vai va, vu va

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

• Performing a fuzzy search may retrieve terms with similar spellings: so anh tu nang xa hoi. hieu ve ((cac xuc) OR (cam xuc)) ((ban hanh) or (va thanh)) vi va trien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so anh tu nang xa hoi. hieu ve ((cac xuc) OR (cam xuc)) ((ban hanh) OR (va thanh)) vi va trien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so anh tu nang xa hoi. hieu ve ((cac xuc) OR (cam xuc)) ((ban hanh) or (va thanh)) vi va trien".
• Adding a wildcard symbol may retrieve word variants: so anh tu nang xa hoi. hieu ve ((cac xuc) OR (cam xuc)) ((ban hanh) or (va thanh)) vi va trien*.
