Perhaps you should try some spelling variations:
hieu hien » bieu hien, dieu hien, chieu chien
truong va » truong dai, truong cao, truong dao
trung va » trang va, trung ha, trung tam
danh vi » hanh vi, dinh vi, danh di
so sach » so sanh, bo sach, hoc sach
nang ma » tang ma, sang ma, nang cao
ly nang » ky nang, ly hang, ly vang
co sach » bo sach, cuon sach, hoc sach
ma hoi » mai hoi, xa hoi, ma hoa
vi cua » vai cua, di cua

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: ((so sach) OR (co sach)) ly nang ma hoi. hieu hien dai ((trung va) OR (truong va)) danh vi cua vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (co sach)) ly nang ma hoi. hieu hien dai ((trung va) OR (truong va)) danh vi cua vat~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (co sach)) ly nang ma hoi. hieu hien dai ((trung va) OR (truong va)) danh vi cua vat*.
