Perhaps you should try some spelling variations:
thanh lap » phan lap, thanh hai, thanh van
hanh lai » hanh lam, hanh tai, thanh loi
su triet » su viet, su tien, ve triet
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
cac xuc » cam xuc, cac nuoc, chat xuc
xuc va » duc va, tuc va, luc va

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

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