Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
dao tren » dat tren, dao tien, dau tren
hieu van » hieu va, thien van, lieu va
van hanh » ban hanh, van anh, van ban
chat xuc » chat huu, cam xuc, chao xu
van chat » cao chat
su sach » so sach, vu sach
tu cach » tu cac
va dao » ca dao
x hoi » xa hoi, o hoi, x ho

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 cach) OR (su sach)) ky nang x hoi. hieu van chat xuc ((van hanh) OR (van thanh)) va dao tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (su sach)) ky nang x hoi. hieu van chat xuc ((van hanh) OR (van thanh)) va dao tren~".
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (su sach)) ky nang x hoi. hieu van chat xuc ((van hanh) OR (van thanh)) va dao tren*.
