Perhaps you should try some spelling variations:
cau treo » cau theo, cau tren, cau triet
van hanh » van thanh, ban hanh, van anh
kho tang » cao tang
thu san » thuy san, thu ban, phu san
xuc van » duc van, luc van, vuc van
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
ky tang » ky nang, ky dang, ky trong
cua duc » cua tuc, cua nuoc, cua quoc
ve cac » va cac, vien cac

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: thu san ((ky tang) OR (kho tang)) xa hoi. hieu ve cac xuc van hanh vi ((cau treo) OR (cua duc))~.
• Adding a wildcard symbol may retrieve word variants: thu san ((ky tang) or (kho tang)) xa hoi. hieu ve cac xuc van hanh vi ((cau treo) or (cua duc))*.
