Perhaps you should try some spelling variations:
trong chuan » thong chuan, trong chan, trong thuan
phuong linh » phuong binh, phuong trinh, cuong linh
hanh trong » hanh trang, anh trong, hinh trong
chuan dung » chan dung, chuyen dung, chua dong
phuong lan » phuong la, thuong lan, phuong tran
hien xanh » hien nhanh, chieu xanh, hien khanh
hien hanh » dieu hanh
toan cau » toan cao, toan ban, toan tap

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 ((hien xanh) OR (hien hanh)) - hanh trong chuan dung ((phuong lan) OR (phuong linh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (hien hanh)) - hanh trong chuan dung ((phuong lan) OR (phuong linh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien hanh)) - hanh trong chuan dung ((phuong lan) OR (phuong linh)) toan cau*.
