Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
cau tren » cu tren, dau tren, ca tren
hieu van » hieu va, thien van, lieu va
va thanh » gia thanh, ban thanh, va tinh
cau luc » cau truc, cau phuc
vai cau » va cau, van cau, vai cac
te sach » toc sach
nang xa » nang x, lang xa, nang ma
cam luc » cam xuc

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) or (thu hoach)) ky nang xa hoi. hieu van ((cam luc) OR (cau luc)) va thanh vai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thu hoach)) ky nang xa hoi. hieu van ((cam luc) OR (cau luc)) va thanh vai cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thu hoach)) ky nang xa hoi. hieu van ((cam luc) OR (cau luc)) va thanh vai cau tren*".
