Suppose you got the certificate of completion before July-September, 20 10.

Now I have passed all the exams for credits and completed all the credits I deserve.

Then the graduation time after changing the diploma is the current time, not your original normal graduation time.

People's Republic of China (PRC) (China) Higher Education Law

(Adopted at the Fourth Session of the Ninth NPC Standing Committee)

1August 29, 998

Article 48 Students shall complete all the courses and all the teaching links specified in the education and teaching plan within the study period specified by the college. Those who fail to meet the graduation requirements will be granted graduation and a certificate of completion will be issued.

Graduates can apply for a make-up exam within one year after graduation according to the time specified by the college (failure to pass the make-up exam is regarded as a waiver and will not be made). Those who pass the examination or obtain the vocational certificate or skill certificate stipulated in the teaching plan can renew their graduation certificates with their graduation certificates. Students who have completed their studies due to unqualified conduct (including disciplinary action) may apply by themselves one year after graduation and provide proof of no bad performance. With the approval of the college, the graduation certificate can be changed into a graduation certificate. The graduation time of all renewal diplomas shall be filled in according to the renewal time.
