Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
va trien » va truyen, va thiet, va tuyen
pham cuc » pham chuc, pham duc, pham cua
sach ty » sach y, sach tu, sach thu
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
cam cuc » cam xuc, cham cuu
sai ky » sac ky
vai va » mai va, dai va, hai va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (sai ky)) nang xa hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh vai va trien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sai ky)) nang xa hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh vai va trien*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sai ky)) nang xa hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh vai va trien*".
