Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hanh hai » thanh hai, nhanh hai, hang hai
van hanh » van thanh, ban hanh, van anh
duc van » duc va, duc tan, duc manh
ky dang » ky nang, ky danh
dang ha » dong ha, dung ha, lang ha
hieu va » hieu qua
cam duc » cam xuc, cao duc, pham duc
ha hoi » hoa hoi, ha noi, xa hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky dang ha hoi. ((hieu va) or (lieu va)) cam duc van hanh hai ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky dang ha hoi. ((hieu va) OR (lieu va)) cam duc van hanh hai ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky dang ha hoi. ((hieu va) or (lieu va)) cam duc van hanh hai ((cua triet) OR (su triet))*".
