Perhaps you should try some spelling variations:
thuc van » thuc vat, thuc dan, thuc va
hanh vai » hanh vi, hanh va, hanh tai
te sach » toc sach
hieu ve » hieu va, hieu van
tuc van » truc van, tuc va, duc van
vai cuu » vai cua
cuu tre » cua tre, cau tren, cau treo
y lang » o lang, tay lang, yen lang
_ lang » o lang, _ land
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 lang) or (_ lang)) xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y lang) OR (_ lang)) xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y lang) or (_ lang)) xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((y lang) or (_ lang)) xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vai cuu tre*.
