Perhaps you should try some spelling variations:
vien cua » viec cua, dien cua, tien cua
thu sai » thu hai, thu tai, thu san
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cao suc » cao duc
va nhan » van nhan, va phan, va nha
sai ky » sac ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sai ky nang xa hoi. hieu ve ((cao suc) OR (cao su)) ((va nhan) or (ca nhan)) vien cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sai ky nang xa hoi. hieu ve ((cao suc) OR (cao su)) ((va nhan) OR (ca nhan)) vien cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sai ky nang xa hoi. hieu ve ((cao suc) OR (cao su)) ((va nhan) or (ca nhan)) vien cua te".
• Adding a wildcard symbol may retrieve word variants: thu sai ky nang xa hoi. hieu ve ((cao suc) OR (cao su)) ((va nhan) or (ca nhan)) vien cua te*.
