Perhaps you should try some spelling variations:
cau triet » cau trieu, su triet, cua triet
thu sach » tu sach, thuat sach, thuoc sach
gian lan » gian lang, gian dan, giang van
chat xuc » chat huu, cam xuc, chao xu
hieu van » hieu va, thien van, lieu va
lan cau » van cau, lan dau, ban cau
va gian » va gianh, van gian, va giai
te sach » toc sach
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (thu sach)) ty nang xa hoi. hieu van ((hac xuc) OR (chat xuc)) va gian lan cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thu sach)) ty nang xa hoi. hieu van ((hac xuc) OR (chat xuc)) va gian lan cau triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thu sach)) ty nang xa hoi. hieu van ((hac xuc) OR (chat xuc)) va gian lan cau triet*".
