Perhaps you should try some spelling variations:
hieu va » lieu va, hieu qua
xa kinh » va kinh, xa sinh, xa tinh
cam tuc » cam xuc, cam tu, nam thuc
tang ma » mang may, tang van
ky tang » ky nang, ky dang, kho tang
ma hoi » mai hoi, xa hoi, ma hoa
va cam » va cham, va cac, va cao
vu san » va san, vu ban
di cua » doi cua, de cua, do cua
vu sai » vu hai, vu dai, vu tai

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