Perhaps you should try some spelling variations:
hanh truong » hanh trong, anh truong, manh truong
truong dao » truong dai, truong cao, truong bo
vang thanh » van thanh, tang thanh, nang thanh
dang thanh » dong thanh, dang hanh, hoang thanh
chuc danh » chuc nganh, thuc hanh, chuc nang
dao trong » tao trong, dat trong, dot trong

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: hoi chuc danh - hanh truong dao trong cong ((vang thanh) OR (dang thanh)) phan~.
• Adding a wildcard symbol may retrieve word variants: hoi chuc danh - hanh truong dao trong cong ((vang thanh) or (dang thanh)) phan*.
