Perhaps you should try some spelling variations:
chuan dao » chuan doan, chuan iso, chuan ha
chuc dao » chuc danh, chuc giao, cho dao
danh dai » danh dau, danh di, danh sai
hieu va » lieu va, hieu qua
cua tre » cuu tre, cua triet, dua tren
te cao » te bao
cua te » cua tu
va am » va lam, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: te cao ky nang x ho. hieu va am ((chuc dao) OR (chuan dao)) danh dai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cao ky nang x ho. hieu va am ((chuc dao) OR (chuan dao)) danh dai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cao ky nang x ho. hieu va am ((chuc dao) OR (chuan dao)) danh dai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: te cao ky nang x ho. hieu va am ((chuc dao) OR (chuan dao)) danh dai ((cua tre) or (cua te))*.
