Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, thanh san
sach duy » sach dung, sach duoc, sach dao
khanh xa » khanh hoa, khanh tra, khanh van
te sach » toc sach
cuu tre » cua tre, cau tren, cau treo
xuc va » duc va, tuc va, luc va
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac

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 duy khanh xa hoi. hieu ((ve cam) or (ve cac)) xuc va ((thanh tai) OR (doanh tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach duy khanh xa hoi. hieu ((ve cam) OR (ve cac)) xuc va ((thanh tai) OR (doanh tai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach duy khanh xa hoi. hieu ((ve cam) or (ve cac)) xuc va ((thanh tai) OR (doanh tai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach duy khanh xa hoi. hieu ((ve cam) or (ve cac)) xuc va ((thanh tai) OR (doanh tai)) cuu tre*.
