Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
chieu sach » chinh sach, chiet tach, chieu sang
dong huong » dong thuong, dong duong, cong huong
huong manh » duong manh, hung manh, luong manh
bien tinh » bi tinh, yen tinh, diep tinh
hanh nang » anh nang, ganh nang, hanh mang
nang quan » ban quan, nang suat
quan dong » quang dong, quan long, quan hoang
manh toan » thanh toan, anh tuan, tinh toan
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: theo ((((chieu tinh) OR (bien tinh))) OR (chieu sach)) - hanh nang quan dong huong manh toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu tinh) or (bien tinh))) or (chieu sach)) - hanh nang quan dong huong manh toan cau*.
