However, a 27-second video of the new cartoon, released several days earlier, has made waves on the social media. The new images of the Haier Brothers are a far cry from those in the memories of devoted fans.

Many netizens responded in the comment section of the video, saying they really looked forward to the new cartoon. But more people ranted about the alteration of the images and some even questioned why the original Haier Brothers were not kept.

"The video online is not yet an official trailer," said a staff member for the cartoon's production when he responded to the complaints.
