Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
tu sach » thu sach, su sach, tu cach
vai cuu » vai cua
duc van » duc va, duc tan, duc manh
xuc van » luc van, vuc van, xuc ban
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
te sach » toc sach
cuu tre » cua tre, cau tren, cau treo
va dau » va dao
2 nang » v nang

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) or (te sach)) 2 nang xa hoi. hieu va dau ((xuc van) OR (duc van)) thanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) 2 nang xa hoi. hieu va dau ((xuc van) OR (duc van)) thanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) 2 nang xa hoi. hieu va dau ((xuc van) OR (duc van)) thanh vai cuu tre*".
