Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
thi hang » thi hanh, thi nang, thi thanh
thi hong » thi cong, thi phuong, thi hanh
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
vai cua » dai cua, hai cua, lai cua
ve cam » ve cham, ve cac, va cam
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((thi hang) OR (thi hong)) xa hoi. hieu ve cam ((xuc va) OR (tuc va)) thanh vai cua vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thi hang) or (thi hong)) xa hoi. hieu ve cam ((xuc va) OR (tuc va)) thanh vai cua vat~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((thi hang) or (thi hong)) xa hoi. hieu ve cam ((xuc va) OR (tuc va)) thanh vai cua vat*.
