Isn't Namikaze Minato dead? Why do people call him "Jin Shanshan invincible ninja"?

The four generations of Huo Ying in the cartoon were resurrected by orochimaru, and a yellow flashing pattern appeared, similar to that of Naruto bijuu.

Namikaze Minato is the yellow flash of konoha.

Relative Naruto's hairstyle is red+yellow = orange (golden), so Naruto is also called golden flash.
