Perhaps you should try some spelling variations:
thien van » thi van
van cham » van chat, van tham, va cham
cham xuc » cam xuc, chat xuc, cham soc
van phan » van phong, van thanh, luan phan
tu sach » thu sach, te sach, tu cach
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
van han » van hanh, van nhan, van hoan
tai va » thai va, mai va, tri va
thiet* » thieu*

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) OR (su sach)) ky nang xa hoi. thien van cham xuc ((van han) or (van phan)) tai va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky nang xa hoi. thien van cham xuc ((van han) OR (van phan)) tai va thiet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ky nang xa hoi. thien van cham xuc ((van han) or (van phan)) tai va thiet*".
