According to QQ, in a recent interview, director Wang Zheng frankly said that due to limitations in appearance, Xiao Zheng has a "very narrow acting range", often being arranged in roles that are not suitable for himself.
He advised Tieu Chien's crew to refer to Luu Tung Nhan's "stable step-by-step" roadmap, plan to "change" according to age in a scientific way, otherwise the actors themselves should also soon calculate for the future.
However, Vuong Tinh's statement caused controversy. Many opinions suggest that this director borrowed the advice to criticize Tieu Chien. Because looking at the film genres that the actor has tried in recent years, the assessment of "small acting range" is not true to reality.
From the famous fairy tale "Tran Tinh Muan", to the modern drama "That Dreamy Sea", and recently the ancient-style plot-themed film "Tang Hai Truyen" just aired - becoming one of the most outstanding Chinese dramas of 2025.
What really makes the audience more upset is that Vuong Tinh seems to completely ignore Tieu Chien's efforts. In the audience-saturated black comedy "Dac Nhan Cham De", Tieu Chien not only plays a mechanical worker from the bottom of society, but also shaves his hair, loses nearly 9kg, and painstakingly practices Nanjing dialect.
An impromptu movement to wipe away blood stains that he came up with was also acknowledged by top screenwriter Lan Xiaolong, and even commented by CCTV as "teaserbook acting". Xiao Zheng's recklessness is clearly contrary to the view of "not being arranged for an inappropriate role" that Wang Zheng said.

According to QQ, in Wang Jing's point of view, the part about actors needing to plan for transformation, avoiding being framed with images, is not completely unreasonable. Successful examples like Ta Dinh Phong that he gave also partly reflect the rules of the industry.
Tieu Chien himself has also publicly stated many times that he "does not accept safe zones", proactively participates in difficult topics such as "Dac Nhan Chuan Die", the criteria for choosing films clearly lean towards the complexity of the character rather than commercial safety.
But Vuong Tinh's criticism was considered to be inconsistent with the reality that Tieu Chien continuously joined the film crew and constantly challenged roles with very large differences.
From "Dac Nhan can che" to the next projects such as "Diep bao khong gioi han" and "Tieu thanh luong phuong", his schedule clearly shows his desire to break through.
This has caused a part of netizens to question Wang Jing's motives for speaking, especially when his previous controversies about video editing have raised suspicions of "trying to attract attention".
Tieu Chien's supporters believe that it is time to put aside the prejudice created by the "leading idol" label, because the achievements and data are the most accurate evidence. "Dac Nhan Chuan Mai" has a rate of male audiences increasing to 11.6%, and the ticket buying rate in ranked 3-4 cities exceeds 60%.
Fans declare that these "breaking signals" are much more convincing than one-sided assessments.
