Perhaps you should try some spelling variations:
sinh dai » sinh thai, sinh vat, sinh li
ky tang » ky dang, kho tang, ky trong
hieu va » lieu va, hieu qua
cuu tre » cua tre, cau tren, cau treo
vu sac » vu sach, vu san, va sac
ma hoi » mai hoi, xa hoi, ma hoa
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va

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 tang) OR (ky nang)) ma hoi. hieu va cam xuc va ((sinh dai) OR (si dai)) cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ((ky tang) or (ky nang)) ma hoi. hieu va cam xuc va ((sinh dai) OR (si dai)) cuu tre~".
• Adding a wildcard symbol may retrieve word variants: vu sac ((ky tang) or (ky nang)) ma hoi. hieu va cam xuc va ((sinh dai) OR (si dai)) cuu tre*.
