Duterte may run for vice president of the Philippines? Is the next president her daughter?

The series of policies implemented by Duterte are generally stable in the Philippines. The future can be expected.
After a few days, there are still heated discussions in the Philippines. After all, Lao Du took office as the President of the Philippines on June 30, 2016. Time flies, and I don’t realize it has been 5 years. He will step down in June next year.
According to Philippine law, the election of the president and the vice president are elected separately. The candidates for these two positions may come from two political camps. In other words, even if Duterte is elected vice president of the Philippines in the future, he may not be able to influence the political situation. From this, CNN concluded that Duterte expressed his willingness to run for vice president out of emotional outburst.
However, Duterte's idea of running for vice president may be related to the possibility that his daughter may become the next president of the Philippines.
