Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
thien van » thi van
nam duoc » nam thuoc, da duoc, dat duoc
va thanh » gia thanh, ban thanh, va tinh
cua tre » cua te, cuu tre, cua triet
duoc va » nuoc va, duc va, duoc ma
sach ky » sach y, sach ty, sach kem
danh xa » danh ca, dinh xa, canh xa
sac ky » cac ky, sai ky
cua tu » cua tuc, cua su, cua cu

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sac ky)) danh xa hoi. thien van nam duoc va thanh toan ((cua tre) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) danh xa hoi. thien van nam duoc va thanh toan ((cua tre) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sac ky)) danh xa hoi. thien van nam duoc va thanh toan ((cua tre) or (cua tu))*".
