Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
su sach » so sach, vu sach
ky lang » ky dang, ky tang, tay lang
hieu ve » hieu va, hieu van
xuc van » luc van, xuc ban, thuc van
duc van » duc va, duc tan, duc manh
vai cua » dai cua, hai cua, lai cua
ve cam » ve cham, ve cac, va cam
cua te » cua tu

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 lang) or (ky nang)) xa hoi. hieu ve cam ((xuc van) OR (duc van)) hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky lang) OR (ky nang)) xa hoi. hieu ve cam ((xuc van) OR (duc van)) hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky lang) or (ky nang)) xa hoi. hieu ve cam ((xuc van) OR (duc van)) hanh vai cua te*".
