Perhaps you should try some spelling variations:
nhien viet » nhin viet, nghiep viet, trien viet
trinh viet » ninh viet, trinh vat
viet cua » viec cua, viet ca, viet qua
va trinh » van trinh, va tinh, lap trinh
viet cac » vien cac, viet ca, viet bac
cac xuc » cam xuc, cac nuoc, chat xuc
nang ma » tang ma, sang ma, nang cao
xuc va » duc va, tuc va, luc va
sac ky » cac ky
cua te » cua tu

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: tu ((sac ky) OR (sai ky)) ((nang x) OR (nang ma)) hoi. nhien viet cac xuc va trinh viet cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (sai ky)) ((nang x) or (nang ma)) hoi. nhien viet cac xuc va trinh viet cua te~".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (sai ky)) ((nang x) or (nang ma)) hoi. nhien viet cac xuc va trinh viet cua te*.
