Perhaps you should try some spelling variations:
sang mai » sang ma, sang tai, lang mai
danh lai » danh sai, gianh lai, dinh lam
chau tre » chay tren, chau tho, cho tre
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, luc va, xac va

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 y) or (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (duc va)) danh lai chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach y) OR (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (duc va)) danh lai chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach y) or (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (duc va)) danh lai chau tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach y) or (sac ky)) sang mai hoi. hieu ve cam ((xuc va) OR (duc va)) danh lai chau tre*.
