Perhaps you should try some spelling variations:
van chat » cao chat
danh sai » dung sai, danh bat, danh dau
hieu van » hieu va, thien van, lieu va
sai cua » dai cua, hai cua, lai cua
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
tu sach » thu sach, su sach, te sach
soc va » hoc va, loc va, goc va
doc va » duoc va, hoc va, duc va
tu sac » tu cac, tu san, tu bac

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (tu sach)) ky lang xa hoi. hieu van chat ((soc va) OR (doc va)) danh sai cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky lang xa hoi. hieu van chat ((soc va) OR (doc va)) danh sai cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu sach)) ky lang xa hoi. hieu van chat ((soc va) OR (doc va)) danh sai cua vat*".
