Perhaps you should try some spelling variations:
ve triet » va trien, su triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
danh de » hanh de, dang de, danh di
thuc va » thuc vat, thuc dan, thuc day
dan de » dan den, dang de, van de
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac

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: te sac ky lang xa hoi. hieu ((ve cam) OR (ve cac)) thuc va ((danh de) OR (dan de)) ve triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. hieu ((ve cam) OR (ve cac)) thuc va ((danh de) or (dan de)) ve triet~".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. hieu ((ve cam) OR (ve cac)) thuc va ((danh de) or (dan de)) ve triet*.
