Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
cham cuu » cap cuu, chat cua
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
sach ky » sach y, sach ty, sach kem
cam cuc » cam xuc, pham cuc
sac ky » cac ky, sai ky
vai va » mai va, dai va, hai va
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: tu ((sach ky) or (sac ky)) nang xa hoi. hieu va ((cam cuc) OR (cham cuu)) ban thanh vai va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) nang xa hoi. hieu va ((cam cuc) OR (cham cuu)) ban thanh vai va thiet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sac ky)) nang xa hoi. hieu va ((cam cuc) OR (cham cuu)) ban thanh vai va thiet*".
