I face problem in my chines student visa

On September 3, 2024, I went to China with an X1 visa issued by the Embassy of the Peoples Republic of China in Islamabad, Pakistan. The Guangzhou Immigration Bureau does not allow me to enter China and only gave me reason, which is that they said I did not obtain a visa according to regulations and also had problem with an T visa, which I got from Huaian immigration bureau , They said I should return to Pakistan to apply for a new X1 visa and bring the new visa back to China. Plz solve it As I mentioned earlier after denied entry ,The guangzhou immigration bureau cancel my X1 visa and They said I should return to Pakistan to apply for a new X1 visa and bring the new visa back to China and also mentioned a problem in T Visa, kindly solve my problems
