Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
ve cham » va cham, ve chat, vu cham
mai hoi » mai khoi, lai hoi, mai doi
va hanh » van hanh, va thanh, va danh
dai hoi » dai hoc, dai hai, dai moi
vi cua » vai cua, di cua
tuc va » thuc va, truc va, tuc xa
tu cam » tu cham, tu cac, tu nam
cam ky » cao ky, cac ky
ve cac » va cac, vien cac

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 cam ky nang ((mai hoi) OR (dai hoi)). hieu ((ve cac) OR (ve cham)) tuc va hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cam ky nang ((mai hoi) or (dai hoi)). hieu ((ve cac) or (ve cham)) tuc va hanh vi cua tre*.
