Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
vu khach » vu khanh, vu khac, vay khach
danh ban » doanh ban, danh bat, danh bac
truc va » thuc va, thuc vat, trung va
ban cua » ban quan
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
tuc va » thuc va, tuc xa, duc va
ve cac » va cac, vien cac

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) or (vu khach)) ky nang xa hoi. hieu ve cac ((tuc va) OR (truc va)) danh ban cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu khach)) ky nang xa hoi. hieu ve cac ((tuc va) OR (truc va)) danh ban cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu khach)) ky nang xa hoi. hieu ve cac ((tuc va) OR (truc va)) danh ban cua triet*".
