Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van pham » san pham, van phan, van phat
va thanh » gia thanh, ban thanh, va tinh
tu cach » tu cac
te sach » toc sach
nang xa » nang x, lang xa, nang ma
do su » do sut, co su, da su
do tu » co tu, de tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (te sach)) ky nang xa hoi. hieu van pham duc va thanh ((do su) OR (do tu)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (te sach)) ky nang xa hoi. hieu van pham duc va thanh ((do su) OR (do tu)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (te sach)) ky nang xa hoi. hieu van pham duc va thanh ((do su) OR (do tu)) triet*".
