Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
va thanh » gia thanh, ban thanh, va tinh
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
su tien » su kien, su hien, tu tieng
hoc hoi » hoc khoi, hoc hoa, hoc noi
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
ho hoi » hoa hoi, hoi hoi, co hoi
ve cam » ve cham, va cam, ve cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky nang ((ho hoi) OR (hoc hoi)). hieu ((ve cam) or (ve cac)) xuc va thanh lai su tien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang ((ho hoi) OR (hoc hoi)). hieu ((ve cam) OR (ve cac)) xuc va thanh lai su tien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang ((ho hoi) OR (hoc hoi)). hieu ((ve cam) or (ve cac)) xuc va thanh lai su tien".
• Adding a wildcard symbol may retrieve word variants: vu sach ky nang ((ho hoi) OR (hoc hoi)). hieu ((ve cam) or (ve cac)) xuc va thanh lai su tien*.
