Perhaps you should try some spelling variations:
thanh phan » thanh pho, thanh san, thanh toan
cham xuc » chat xuc, cham soc, pham duc
sang tai » hang tai, sang tao, tang tai
tai khoa » da khoa, noi khoa
tu sach » thu sach, su sach, te sach
hanh va » hang va, hanh vi
cuu tre » cua tre, cau tren, cau treo
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
ky sang » ky nang, ky dang, ky tang

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 sach ky sang tai khoa. hieu ve ((cham xuc) OR (cam xuc)) va ((thanh phan) OR (hanh va)) cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky sang tai khoa. hieu ve ((cham xuc) OR (cam xuc)) va ((thanh phan) or (hanh va)) cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky sang tai khoa. hieu ve ((cham xuc) OR (cam xuc)) va ((thanh phan) or (hanh va)) cuu tre*.
