The video is said to originate from chinese social media and refers to the credible shotdown of at least one Rafael jet India has purchased from France in 2019 during the recent clashes between India and Pakistan.
The song used for the parody is Tunak Tunak Tun by Indian singer Daler Mehndi who mocked his critics with the song claiming he would only be successful because of women dancing in his music videos.
Pakistan is using J-17 jets which have been jointly developed by China and Pakistan and are claimed to have shot down the Rafael jets. This would be the first time these jets have been in combat against other fighter jets.
So from a Chinese perspective it is their jets being superior to the jets used by India. Also China has an ongoing border dispute with India, albeit there people typically fight with batons and throwing rocks at each other, rather than shooting.
