Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu xanh » chieu sach, chieu sang, chieu tinh
chuc danh » chuc nganh, thuc hanh, chuc nang
hanh tang » hanh trang, anh tang, hanh mang
cong tinh » cong trinh, cong vinh, long tinh
toan tap » toan ban
tang va » trang va, tang van, thang va

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: theo ((chuc danh) OR (chieu xanh)) - hanh tang va nhung cong tinh toan tap~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chieu xanh)) - hanh tang va nhung cong tinh toan tap*.
