Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
cua triet » cua viet, su triet, va triet
van thanh » ban thanh, van tuan
ky lang » ky nang, ky dang, ky tang
lang ha » long ha
cua tre » cua te, cuu tre, dua tren
hieu ve » hieu va, hieu van
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ha hoi » hoa hoi, ha noi, xa hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky lang ha hoi. hieu ve ((tao duoc) or (pham duc)) van thanh hai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky lang ha hoi. hieu ve ((tao duoc) OR (pham duc)) van thanh hai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky lang ha hoi. hieu ve ((tao duoc) or (pham duc)) van thanh hai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: su sac ky lang ha hoi. hieu ve ((tao duoc) or (pham duc)) van thanh hai ((cua tre) OR (cua triet))*.
