Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
nang xay » dang xay, nganh xay, nang xuan
chat xuc » chat huu, cam xuc, chao xu
va thanh » gia thanh, va tinh, le thanh
su sach » so sach, vu sach
luu tre » cuu tre, luy tre
xay hoi » xa hoi, tay hoi, cay phoi
hieu va » lieu va, hieu qua
va chat » van chat, va phat, cao chat
sach ky » sac ky, sach y, sach ty
tru » truc

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xay hoi. hieu va chat xuc ((va thanh) OR (ban thanh)) van ((luu tre) or (luu tru))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xay hoi. hieu va chat xuc ((va thanh) OR (ban thanh)) van ((luu tre) OR (luu tru))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xay hoi. hieu va chat xuc ((va thanh) OR (ban thanh)) van ((luu tre) or (luu tru))*".
