The numbers overlap, not the names.
The so-called Mediatek chip and Kirin name is completely misunderstood, the reason for this is because the two chips Tiangu9000 and Kirin 9000 have the number 9000. The current name of Mediatek's high-end chips is Tianji Digital, while Hisilicon's chips are Kirin digital models. It is just a coincidence that the name is the same, in fact, the company is different, the design is different, the process is different, it is completely two different chips.
