We have a formal invitation/ original copies. Is it possible to get the visa in the same day?

Dear sir
Would you please advise us about your working days in the embassy of China in Jordan/Amman. We have a formal invitation/ original copies. We are a group of senior engineers working in Iraq. We are planning to come to Amman on next Sunday 8th of April to get the visa. Is it possible to get the visa in the same day because we are planning to book for the flight to Changahai on the 9 th of April.
Thanking you.
Regards
