Perhaps you should try some spelling variations:
cam truc » cau truc, nam truc, lam truoc
hieu ve » hieu va, hieu van
truc va » thuc va, thuc vat, trung va
va danh » va dinh, va dan, va hanh
so sinh » so sanh, so tinh, cho sinh
ma hoi » mai hoi, xa hoi, ma hoa
y nang » ly nang, v nang, may nang
ve cam » ve cham, ve cac, va cam
va cai » va cac, va bai, va dai
vi ca » vit ca, li ca, va ca

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 sinh ((y nang) OR (ky nang)) ma hoi. hieu ve cam truc va danh ((vi ca) OR (va cai)) viet~.
• Adding a wildcard symbol may retrieve word variants: so sinh ((y nang) or (ky nang)) ma hoi. hieu ve cam truc va danh ((vi ca) or (va cai)) viet*.
