Perhaps you should try some spelling variations:
doi cua » dai cua, hoi cua
va dinh » van dinh, va kinh, va tinh
cam duc » cam xuc, cao duc, nam duoc
tang ma » mang may, tang van
hieu va » lieu va, hieu qua
ky tang » ky nang, ky dang, kho tang
sai ky » sac ky
ma hoi » mai hoi, xa hoi, ma hoa
di cua » dai cua, de cua, do cua
vu sai » vu hai, vu san, vu dai

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 sai ky tang ma hoi. hieu va ((cam duc) OR (pham duc)) va dinh ((di cua) OR (doi cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky tang ma hoi. hieu va ((cam duc) or (pham duc)) va dinh ((di cua) OR (doi cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: vu sai ky tang ma hoi. hieu va ((cam duc) or (pham duc)) va dinh ((di cua) OR (doi cua)) tre*.
