According to Chinese media, in the post saying goodbye to the character after the drama "Bac Thuong" broadcast during CCTV-1's prime time, a work of considerable weight, but Bach Loc only wrote 200 words, he made up to 3 spelling mistakes: confusion of homophones, incorrect use of prepositions and completely wrong use of verbs.

After netizens pointed out the mistake, producer Vu Chinh spoke out to defend Bach Loc, saying that they are artists who "post articles sincerely and directly", no one censors the content, hoping everyone will appreciate that.
However, many viewers objected, saying that Vu Chinh was swapping the concept of "not approving songs" into an expression of "sincerity", while lowering the requirements for basic language proficiency.
The reason why the incident climbed to the trend of popular topics on Weibo is because it touched the issue of controversy about the education of artists.
In February 2023, CCTV published articles criticizing artists involved in academic controversies.
CCTV used an example of a male actor in a Tet movie promotion that could not answer any questions about the character he played, saying he "didn't know how to answer".

These details coincide with Wang Yibo's interview when promoting the movie "Unknown". Therefore, although CCTV did not name him specifically, the public and public opinion believe that the article is implying Wang Yibo.
Previously, this actor had repeatedly misspelled common Chinese characters and mispronounced basic words.
According to media reports, CCTV's article is actually not just about knowing or not knowing how to read.
What is reflected is that when the entertainment industry only values beauty and fame, while knowledge, script analysis ability and investment in roles are not valued, artists will not have the motivation to cultivate those aspects.
And as a result, they are prone to falling into a situation where they cannot answer questions about the character or work.

Or the case of actress Cuc Tinh Y. In a variety show, the MC asked: "A triangle with a larger angle than 90 degrees, what is it called a triangle? ". She frowned and thought for a long time, guessed all the square triangles and then the even triangles, and finally cautiously said in uncertainty: "Prison triangle?".
This clip then continuously appeared in satirical videos, showing the gap between "cultural foundation" and "images polished in front of the camera".
What is more noteworthy is how Cuc Tinh Y talks about the character she plays. When reporters asked who the character was, what his personality was, and what his inner motives were, she only repeated the phrase: "Arrogant but warm", unable to delve into any other layer of meaning.
According to Sohu, this is not necessarily a problem of lack of knowledge, but largely due to expressive ability.
When a person's language system does not have the pre-existing "personnel analysis" thinking, then all roles are ultimately simplified into a few words describing personality.
