Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
thue nang » thien nang, thuat nang, chuc nang
thi nang » thi cong, ki nang, thi hanh
van hanh » ban hanh, van anh, van ban
te sach » toc sach
vai cua » dai cua, hai cua, lai cua
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
ve cac » va cac, vien cac
cua cu » cua chu, cua cau, cua su

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 ((thue nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((van hanh) or (van thanh)) vai cua cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thue nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((van hanh) OR (van thanh)) vai cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thue nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((van hanh) or (van thanh)) vai cua cu".
• Adding a wildcard symbol may retrieve word variants: te sach ((thue nang) OR (thi nang)) xa hoi. hieu ve cac xuc ((van hanh) or (van thanh)) vai cua cu*.
