Perhaps you should try some spelling variations:
nganh thanh » nhanh thanh, danh thanh, nhanh thang
chuc nganh » chuc nang, hoc nganh, cac nganh
dau tren » dau tien, dat tren, dau tieng
thanh di » thanh doi, thanh de, thanh do
ve cham » va cham, ve chat, vu cham
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
ve cam » va cam, ve cai, ve cau
di dau » doi dau, bi dau, di du
ve cac » va cac, vien cac

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