Perhaps you should try some spelling variations:
chiet tach » chieu sach
hanh trinh » canh tranh, hanh chinh
lang nong » hang nong, lang dong, lang song
ho chiet » ho chieu, ho thiet, hoc thiet
trinh va » trinh van, trinh vat, trinh ve
dan toan » van toan, dan than, manh toan
van tuan » van quan, van ban, anh tuan
va lang » va nang, hoa lang

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - hanh trinh va lang nong ((dan toan) OR (van tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - hanh trinh va lang nong ((dan toan) OR (van tuan)) cau*.
