Perhaps you should try some spelling variations:
manh thanh » danh thanh, minh thanh, manh thang
thanh tai » thanh hai, thanh toan, doanh tai
tai cuu » tai cuc, tai buu, tai cua
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach 2, sach vay
va cam » va cham, va cac, va cao
ve cam » ve cham, ve cac, 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: tu ((sach v) OR (sach y)) nang xa hoi. hieu ((ve cam) or (va cam)) suc manh thanh tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach v) OR (sach y)) nang xa hoi. hieu ((ve cam) OR (va cam)) suc manh thanh tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach v) OR (sach y)) nang xa hoi. hieu ((ve cam) or (va cam)) suc manh thanh tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach v) OR (sach y)) nang xa hoi. hieu ((ve cam) or (va cam)) suc manh thanh tai cuu tre*.
