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
tu ban » thu ban, te ban
ve cac » va cac, vien cac
vi cua » vai cua, di cua
anh vi » hanh vi, anh va, anh ve
cua te » cua tu
ve cau » ke cau, va cau, le cau
ban ky » van ky, dan ky
ve cai » va cai, ve tai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ban ky lang xa hoi. hieu ((((ve cai) OR (ve cau))) or (ve cac)) duc tuan anh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ban ky lang xa hoi. hieu ((((ve cai) OR (ve cau))) OR (ve cac)) duc tuan anh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ban ky lang xa hoi. hieu ((((ve cai) OR (ve cau))) or (ve cac)) duc tuan anh vi cua te*".
