Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
sanh ky » sang ky, nganh ky, thanh ky
vai cua » dai cua, hai cua, lai cua
tru ban » truc ban, thu ban, tu ban
cac tru » ca tru, cac tro, cac thu
hieu ve » hieu va, hieu van
nang ma » tang ma, sang ma, nang cao
hanh ky » hanh kem
ma hoi » mai hoi, xa hoi, ma hoa
di cua » dai cua, doi cua, de cua
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: so ((sanh ky) OR (hanh ky)) nang ma hoi. hieu ve cac tru ban thanh ((di cua) OR (vai cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sanh ky) OR (hanh ky)) nang ma hoi. hieu ve cac tru ban thanh ((di cua) or (vai cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: so ((sanh ky) OR (hanh ky)) nang ma hoi. hieu ve cac tru ban thanh ((di cua) or (vai cua)) triet*.
