According to Dan Tri reporter, as of July 14, the MV "A Duck" is no longer displayed on the children's YouTube channel called "Heo Con".
When searching for this title, users only see a few other versions, with voices and images that are not the same as the MV that set the record of 1 billion views. The highest number of views in the remaining versions also only stops at nearly 78 million.

The reason for the disappearance of the MV is still a mystery. Up to now, YouTube and the channel owner have not given an official response. However, this incident has made many viewers, especially parents, regretful.
For many families, A Duck is not only a music video but also a close "companion", helping children both entertain and learn through familiar melodies.
Many parents and video lovers hope the song will return soon.
“This is my child’s favorite video, I watch it every day without getting bored. I hope the MV will return soon to accompany my child during their entertainment hours,” shared Ms. Linh (Ha Dong, Hanoi ).
Some other opinions also said that, with such a "huge" number of views, the possibility of the MV having copyright problems is possible, especially when the original music has been performed by many artists before. However, all of this is still just speculation.
The MV A Duck was posted on YouTube in August 2019. The MV impressed with its vivid and colorful 3D animation, telling the story of a white mother duck leading 5 yellow ducklings swimming across a pond - just like the familiar lyrics.
Many viewers commented that the video is cute, familiar, with a cheerful and memorable melody, especially suitable for young children. Many parents even jokingly call it “mealtime music” for millions of Vietnamese children.
In June 2024, A Duck officially reached the milestone of 1 billion views, becoming the first Vietnamese music video to achieve this on the YouTube platform.
As of mid-June 2025, before disappearing, the video was still steadily increasing by more than 1 million views per day and receiving 2.2 million likes - an impressive number for a music product for children.

The song Mot con vit was said to have been composed by musician Kim Duyen in 1988. The MV was performed by many child singers such as Xuan Mai, Thao Nhu, Khanh Linh... However, the version performed by Xuan Mai in 1998, when she was only 3 years old, was the most successful and well-received.
Although it was released many years before the development of social media platforms, the song's cheerful, memorable and familiar melody is still "memorized" by Vietnamese audiences through many generations, becoming one of the most famous and familiar children's songs.
The overwhelming success of the 3D animated version of the MV "A Duck" on YouTube also reflects the strong vitality of children's music in the digital space.
Without the need for extensive promotion, children's music products still maintain a stable number of views every day, even more durable than many popular music videos.
In the Vietnamese children's music market, many other videos have also achieved impressive views, such as Bong bong bang bang . The version performed by the 365 Band group has reached over 590 million views, while the version performed by child singer Bao Ngu has surpassed 600 million views.
Globally, Baby Shark - an English song for children - still holds the record for the most viewed video in YouTube history. Up to now, this MV has surpassed 15 billion views, far surpassing other famous products such as: Despacito, Wheels on the Bus , Johny Johny Yes Papa or Bath Song .
This achievement once again affirms the strong position of children's music in global digital content consumption behavior.
