Perhaps you should try some spelling variations:
thuoc sach » hoc sach, nuoc sach, thuat sach
thanh vai » thanh hai, thanh van, thanh tai
cham luc » nhan luc, cham cuu, chat lua
va thanh » gia thanh, ban thanh, va tinh
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cua tre » cuu tre, cua triet, dua tren
cua te » cua tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky nang xa hoi. hieu va ((cham luc) OR (cham soc)) va thanh vai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky nang xa hoi. hieu va ((cham luc) OR (cham soc)) va thanh vai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky nang xa hoi. hieu va ((cham luc) OR (cham soc)) va thanh vai ((cua tre) or (cua te))*".
