Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
bach van » bach dan, cach van, bach dang
sach dao » lanh dao
cham xuc » cam xuc, chat xuc, cham soc
van hanh » ban hanh, van anh, van ban
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
kien » bien, vien, tien

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((bach van) or (sach dao)) nang xa hoi. hieu ve cham xuc ((van hanh) OR (van thanh)) va su kien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((bach van) OR (sach dao)) nang xa hoi. hieu ve cham xuc ((van hanh) OR (van thanh)) va su kien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((bach van) or (sach dao)) nang xa hoi. hieu ve cham xuc ((van hanh) OR (van thanh)) va su kien".
• Adding a wildcard symbol may retrieve word variants: su ((bach van) or (sach dao)) nang xa hoi. hieu ve cham xuc ((van hanh) OR (van thanh)) va su kien*.
