Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
van thanh » ban thanh, van tuan
chat xuc » chat huu, cam xuc, chat cua
ky tang » ky nang, ky dang, kho tang
dan hoc » van hoc, dai hoc, toan hoc
vai cua » dai cua, hai cua, lai cua
hieu vu » hieu va, hieu ve, hieu su
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai 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 tang ((dan hoc) OR (dan toc)). hieu vu ((chat xuc) OR (chao xu)) van thanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang ((dan hoc) or (dan toc)). hieu vu ((chat xuc) OR (chao xu)) van thanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky tang ((dan hoc) or (dan toc)). hieu vu ((chat xuc) OR (chao xu)) van thanh vai cua te*.
