Database error: Invalid SQL: update sponsors set status=-1 where end_date<='2006-07-22'
MySQL Error: 1146 (Table 'chinese.sponsors' doesn't exist)
Session halted.

What does this mean ?

The clue is here:
Table 'chinese.sponsors' doesn't exist

That is saying the table sponsors doesnt exists within the chinese database. Check that your have spelt your table correctly and that your are using the correct database.
