Perhaps you should try some spelling variations:
luoc can » luc canh, hoc can, luoc dai
hanh vai » hanh vi, hanh va, hanh tai
va trien » va truyen, va thiet, va tuyen
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
duc van » duc va, duc tan, duc manh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ma hoi » mai hoi, xa hoi, ma hoa
ve cac » va cac, vien cac
vai va » mai va, dai va, hai va

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: te sac ky nang ma hoi. hieu ve cac ((duc van) OR (luoc can)) hanh vai va trien~.
• Adding a wildcard symbol may retrieve word variants: te sac ky nang ma hoi. hieu ve cac ((duc van) or (luoc can)) hanh vai va trien*.
