Perhaps you should try some spelling variations:
truong cua » truong ca, truong quan, truong cao
nhung cong » dung cong, thong cong, hang cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung cua » trung tuan, trung cap, dung cua
cong doan » cong dan, cong hoan, dong doanh
hoc hieu » hoc thieu, hoc hien, doc hieu
phan cac » nhan cach, phan dau, phan lap

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: hoc hieu manh - hanh ((trung cua) OR (truong cua)) nhung cong doan ((phan tu) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - hanh ((trung cua) OR (truong cua)) nhung cong doan ((phan tu) or (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - hanh ((trung cua) OR (truong cua)) nhung cong doan ((phan tu) or (phan cac))*.
