Perhaps you should try some spelling variations:
loai tren » la tren, thai tren
cham xuc » cam xuc, chat xuc, pham duc
van hanh » van thanh, ban hanh, van anh
cau tren » cu tren, dau tren, ca tren
thu sac » thu sach, thu san, thu xac
ky dinh » ky sinh, ky danh, ky kinh
dinh xa » dinh ba, dinh va, dinh xu
hieu vu » hieu va, hieu ve, hieu su
sac ky » cac ky, sai ky

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 sac ky dinh xa hoi. hieu vu ((cham xuc) OR (cham soc)) van hanh vi ((cau tren) OR (loai tren))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky dinh xa hoi. hieu vu ((cham xuc) OR (cham soc)) van hanh vi ((cau tren) or (loai tren))~".
• Adding a wildcard symbol may retrieve word variants: thu sac ky dinh xa hoi. hieu vu ((cham xuc) OR (cham soc)) van hanh vi ((cau tren) or (loai tren))*.
