Perhaps you should try some spelling variations:

chua xang » chua nang, chuc nang, chu bang
hanh hinh » hanh chinh, hanh tinh, hanh dinh
chu xanh » chu manh, chieu xanh, chuc danh

phan cac » nhan cach, phan dau, phan lap

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: "theo ((chu xanh) OR (chua xang)) - hanh hinh cua ((thong cong) OR (trong cong)) van phan cac~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chua xang)) - hanh hinh cua ((thong cong) OR (trong cong)) van phan cac*.
