Perhaps you should try some spelling variations:
nhanh long » thanh long, nhanh lang, nhanh song
nhanh dong » hanh dong, nhanh chong, anh dong
phuong dan » phuong danh, phuong doan, huong dan
chi danh » chi dan, chi anh, chi dinh
cua bang » chua bang, cua ban, cua dang
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban
doi chi » doi khi

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

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi danh - ((nhanh long) OR (nhanh dong)) cua bang phuong dan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi danh - ((nhanh long) OR (nhanh dong)) cua bang phuong dan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi chi danh - ((nhanh long) OR (nhanh dong)) cua bang phuong dan ((toan tai) or (toan ban))*.
