Perhaps you should try some spelling variations:
thieu bien » thieu nien, tieu bieu, hien bien
su triet » su viet, su tien, ve triet
chat xuc » chat huu, cam xuc, chao xu
hanh vai » hanh va, hanh tai, hanh van
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
cac xuc » cam xuc, cac nuoc, cac cuoc
nang xa » nang x, lang xa, nang ma

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. thieu bien ((cac xuc) OR (chat xuc)) va ((hanh vai) or (hanh vi)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. thieu bien ((cac xuc) OR (chat xuc)) va ((hanh vai) OR (hanh vi)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. thieu bien ((cac xuc) OR (chat xuc)) va ((hanh vai) or (hanh vi)) su triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. thieu bien ((cac xuc) OR (chat xuc)) va ((hanh vai) or (hanh vi)) su triet*.
