Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
cua trong » cua truong, cua trung, ca trong
qua trong » quan trong, qua trinh, qua song
theo kha » theo phap, thao khoa, theo chu
kha nang » phap nang, ky nang, ki nang
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan ban
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: theo kha nang - hanh trinh ((cua trong) OR (qua trong)) cong dan ((toan tai) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: theo kha nang - hanh trinh ((cua trong) or (qua trong)) cong dan ((toan tai) or (toan cao))*.
