Perhaps you should try some spelling variations:
thanh doi » thanh loi, thanh moi, thanh do
cau theo » cau thi, cau tao
lam duoc » nam duoc, luat duoc, lam thuoc
lam xuc » cam xuc
doi cau » doi dau, di cau, doi ca
thi van » thi lan, thi hanh, thi nang
nang xa » lang xa, nang ma, mang xa
sac ky » cac ky, sai ky
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((nang xa) OR (nang x)) hoi. thi van ((lam xuc) or (lam duoc)) gia thanh doi cau theo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((nang xa) OR (nang x)) hoi. thi van ((lam xuc) OR (lam duoc)) gia thanh doi cau theo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((nang xa) OR (nang x)) hoi. thi van ((lam xuc) or (lam duoc)) gia thanh doi cau theo".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((nang xa) OR (nang x)) hoi. thi van ((lam xuc) or (lam duoc)) gia thanh doi cau theo*.
