Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
suc danh » suc canh, sach danh, chuc danh
te sach » toc sach
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
mang xa » mang may, dang xay, mang cua
ve cam » ve cham, ve cac, va cam

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 ((mang xa) or (lang xa)) hoi. hieu ve cam ((suc danh) OR (suc manh)) thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((mang xa) OR (lang xa)) hoi. hieu ve cam ((suc danh) OR (suc manh)) thanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((mang xa) or (lang xa)) hoi. hieu ve cam ((suc danh) OR (suc manh)) thanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((mang xa) or (lang xa)) hoi. hieu ve cam ((suc danh) OR (suc manh)) thanh vai cua tre*.
