Perhaps you should try some spelling variations:
cay phoi » cap phoi, tay hoi, cay cho
sang ky » sang kyo, dang ky, tang ky
hieu ve » hieu va, hieu van
cac duc » cac du, cao duc, cac dac
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
dan ky » van ky
va cay » va cac, va cao, va cai
ve cac » va cac, vien cac
vi cua » vai cua, di cua
cua te » cua tu

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 ((sang ky) OR (dan ky)) va cay phoi. hieu ve cac duc va danh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: tu ((sang ky) or (dan ky)) va cay phoi. hieu ve cac duc va danh vi cua te*.
