Perhaps you should try some spelling variations:
duc tuan » duc thuan, duc tan, duc toan
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
ve cai » va cai, ve cau
ve tai » te tai, de tai, le tai
ve cac » va cac, vien cac
anh vi » hanh vi, anh va, anh ve
vi cua » vai cua, di cua
cua te » cua tu

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 cac ky lang xa hoi. hieu ((((ve cai) OR (ve tai))) OR (ve cac)) duc tuan anh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky lang xa hoi. hieu ((((ve cai) OR (ve tai))) or (ve cac)) duc tuan anh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky lang xa hoi. hieu ((((ve cai) OR (ve tai))) or (ve cac)) duc tuan anh vi cua te*.
