Perhaps you should try some spelling variations:
thanh ket » thanh ke, thanh dat, tinh ket
va trien » va truyen, va tuyen, va tieng
te sach » toc sach
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
sach o » sach lo, sac o, sach y
o lang » hoa lang, hoi lang
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc 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: te sach o lang xa hoi. hieu ve cam xuc va ((thanh ket) or (hanh kem)) ((va trien) OR (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach o lang xa hoi. hieu ve cam xuc va ((thanh ket) OR (hanh kem)) ((va trien) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach o lang xa hoi. hieu ve cam xuc va ((thanh ket) or (hanh kem)) ((va trien) OR (va thiet))".
• Adding a wildcard symbol may retrieve word variants: te sach o lang xa hoi. hieu ve cam xuc va ((thanh ket) or (hanh kem)) ((va trien) OR (va thiet))*.
