Perhaps you should try some spelling variations:
su triet » su viet, ve triet
su tien » su kien, su hien, tu tieng
danh va » doanh va, hanh va, anh va
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
ve cham » va cham, ve chat, ve chim
vu cham » va cham, vu kham, tu cham
va danh » va dinh, va dan, va hanh
te sai » te tai, te bai, te lai
sai ky » sac ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky tang xa hoi. hieu ((ve cham) OR (vu cham)) tu va danh va ((su triet) or (su tien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky tang xa hoi. hieu ((ve cham) OR (vu cham)) tu va danh va ((su triet) OR (su tien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky tang xa hoi. hieu ((ve cham) OR (vu cham)) tu va danh va ((su triet) or (su tien))".
• Adding a wildcard symbol may retrieve word variants: te sai ky tang xa hoi. hieu ((ve cham) OR (vu cham)) tu va danh va ((su triet) or (su tien))*.
