Perhaps you should try some spelling variations:
phuong cong » phuong dong, phung cong, phuong hoang
hanh trung » thanh trung, hanh trang, manh trung
phong cong » phong chong, thong cong, chong cong
mot chieu » doi chieu
trung cua » truong cua, trung tuan, trung cap
ho chieu » theo chieu, hoc thieu, doi chieu
van tuan » van quan, van ban, anh tuan
tuan tap » toan tap, tuan tai, tuyen 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: ((ho chieu) OR (mot chieu)) sach - hanh trung cua ((phuong cong) OR (phong cong)) van tuan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (mot chieu)) sach - hanh trung cua ((phuong cong) OR (phong cong)) van tuan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (mot chieu)) sach - hanh trung cua ((phuong cong) OR (phong cong)) van tuan tap*.
