Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
duc van » duc va, duc tan, duc manh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
tu sac » tu sach, tu cac, tu san
di cua » dai cua, doi cua, de cua
vi cua » vai cua
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve cai » va cai, ve tai, ve cau

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