Perhaps you should try some spelling variations:
tan hanh » tan thanh, tang hanh, toan hanh
hanh tri » thanh tri, hanh tai, hanh trinh
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky dang xa hoi. hieu ((ve cam) or (va cac)) duc tan hanh tri ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky dang xa hoi. hieu ((ve cam) OR (va cac)) duc tan hanh tri ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky dang xa hoi. hieu ((ve cam) or (va cac)) duc tan hanh tri ((cua tre) OR (cuu tre))*".
