Perhaps you should try some spelling variations:
chuc danh » chuc nganh, thuc hanh, chuc nang
thanh hai » thanh phan, thanh hoa, thanh san
hau tieng » cau tieng, dau tieng, mau tieng
xuc danh » quoc danh, luoc danh, muc doanh
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
hai hau » hai chau, dai hau, hai hai
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
x hoi » xa hoi, o hoi, x ho

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. hieu ve cac ((xuc danh) OR (chuc danh)) thanh hai hau tieng~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. hieu ve cac ((xuc danh) OR (chuc danh)) thanh hai hau tieng*.
