Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hang hai » hoang hai, hang tai, thanh hai
ban hang » ngan hang
cham xuc » cam xuc, chat xuc, cham soc
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc ban » duc ban, cuc ban, quoc ban
ky danh » ky anh
ky dang » ky nang
su sach » so sach, vu sach

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 dang) or (ky danh)) xa hoi. hieu ve cham xuc ban hang hai ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky dang) OR (ky danh)) xa hoi. hieu ve cham xuc ban hang hai ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky dang) or (ky danh)) xa hoi. hieu ve cham xuc ban hang hai ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: su sach ((ky dang) or (ky danh)) xa hoi. hieu ve cham xuc ban hang hai ((cua triet) OR (su triet))*.
