Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
tu sach » thu sach, su sach, te sach
sach tu » sach thu, cach tu, sach ty
tu nang » tru nang, tu nong, tu nano
qua cam » qua cham, qua cac, qua ca
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa

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 tu nang x ho. hieu qua cam ((xuc va) OR (tuc va)) thanh lai ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu nang x ho. hieu qua cam ((xuc va) OR (tuc va)) thanh lai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu nang x ho. hieu qua cam ((xuc va) OR (tuc va)) thanh lai ((cua tre) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sach tu nang x ho. hieu qua cam ((xuc va) OR (tuc va)) thanh lai ((cua tre) or (cuu tre))*.
