Perhaps you should try some spelling variations:
mai khoi » mai khoa, tai khoa, dai khoa
cac khoi » cac thoi, cac khoan, cach thoi
cua tre » cua te, cuu tre, cua triet
danh de » hanh de, dan de, dang de
va danh » va dinh, va dan, va hanh
de cua » le cua, te cua, dieu cua
xuc va » duc va, tuc va, luc va
vu sac » vu sach, vu san, va sac
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai

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: vu sac ky nang ((mai khoi) OR (cac khoi)). hieu ((ve cam) OR (ve cac)) xuc va danh de cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang ((mai khoi) OR (cac khoi)). hieu ((ve cam) or (ve cac)) xuc va danh de cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang ((mai khoi) OR (cac khoi)). hieu ((ve cam) or (ve cac)) xuc va danh de cua tre*.
