Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
trinh van » trinh quan, trinh toan, dinh van
trinh han » trinh quan
nang cong » nang song, dang cong, bang cong
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
toan ban » van ban

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: ho ((chieu xanh) OR (chieu sang)) - hanh ((trinh van) OR (trinh han)) nang cong manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - hanh ((trinh van) or (trinh han)) nang cong manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - hanh ((trinh van) or (trinh han)) nang cong manh toan ban*.
