Perhaps you should try some spelling variations:
nganh thanh » nhanh thanh, danh thanh, nhanh thang
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
ve cam » ve cham, ve cac, va cam
di dau » doi dau, bi dau, di cau
di du » li du

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 y nang xa hoi. hieu ve cam xuc ((nganh thanh) or (ngan hang)) ((di dau) OR (di du)) tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu ve cam xuc ((nganh thanh) OR (ngan hang)) ((di dau) OR (di du)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ve cam xuc ((nganh thanh) or (ngan hang)) ((di dau) OR (di du)) tren".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu ve cam xuc ((nganh thanh) or (ngan hang)) ((di dau) OR (di du)) tren*.
