Perhaps you should try some spelling variations:
hai chau » lai chau, ha chau, hat chau
sai cau » lai chau, mai chau
va danh » va dinh, va dan, va hanh
thuc va » thuc vat, thuc dan, thuc day
su sach » so sach, vu sach
va cham » va chat, va tham
y xang » ty xang
ve cam » ve cham, ve cac, va cam
xang x » nang x
x hoi » xa hoi, o hoi, x ho

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 y xang x hoi. hieu ((ve cam) or (va cham)) thuc va danh ((sai cau) OR (hai chau)) tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y xang x hoi. hieu ((ve cam) OR (va cham)) thuc va danh ((sai cau) OR (hai chau)) tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y xang x hoi. hieu ((ve cam) or (va cham)) thuc va danh ((sai cau) OR (hai chau)) tren*".
