Perhaps you should try some spelling variations:
chat duoc » chet duoc, thuat duoc, luat duoc
chat doc » chat hoc, chau doc, thuat doc
van hanh » van thanh, ban hanh, van anh
thi van » thi lan, thi hanh, thi nang
hanh di » hanh vi, hanh de, hang di
cua tre » cuu tre, cua triet, dua tren
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky nang x hoi. thi van ((chat duoc) or (chat doc)) van hanh di ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang x hoi. thi van ((chat duoc) OR (chat doc)) van hanh di ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang x hoi. thi van ((chat duoc) or (chat doc)) van hanh di ((cua tre) OR (cua te))*".
