The list of co-stars of actress Ton Le in the past nearly 10 years only includes familiar names such as Tran Hieu, Dong Dai Vi, La Tan, Truong Gia Dich, Tan Bach Thanh, along with her husband, actor Dang Sieu.
According to media reports, the "closed" cooperation scope to this extent is not common in the entertainment industry. Close friend Liu Tao once revealed the reason why many actors are afraid to cooperate with Sun Li, which is because she is too perfectionist, too focused on every detail.
According to many people in the industry, acting in a movie with Ton Le means "don't think about doing it superficially".
Phuong Trung Tin, who has nearly 30 years of acting experience, once admitted that he was under great pressure when collaborating with Ton Le in "My Nguyet Truyen".
He said that this is one of the movies that makes him most stressed, because Ton Le almost always expresses herself right in one filming session. Meanwhile, he constantly makes mistakes and has to reshoot many times, causing her to re-act with him.
Luu Dao also shared a similar feeling. Every time she knows she will perform with Ton Le the next day, she has to memorize the lines carefully because she doesn't want to affect her co-star. Even, Luu Dao once said: "Performing with Ton Le, I always feel like an amateur actress.

Ton Le's perfectionism has been shown from the early days of her career.
With "Chân Hoàn truyện", 50 volumes of Tôn Lệ's scripts are full of notes. Screenwriter Vương Tiểu Bình was surprised to see pages of paper full of words, even the notes are longer than the lines.
Ton Le also uses different cover colors to divide each psychological stage of Chan Hoan, from the innocent girl who just entered the palace to when the character becomes cold and strong.
Before acting in "My Nguyet Truyen", Ton Le also invited a history lecturer from Phuc Dan University to teach specifically to understand the context and dialogue.
With "An Gia" in 2020, she and screenwriter Luc Luc discussed for an afternoon about how to handle a line.
Notably, with the movie "Beautiful Life" airing in 2025, Ton Le chose the role from 2022 and spent 3 years learning about the character before starting filming.

People who have collaborated with Ton Le have all given her many compliments. Truong Dich likened her to royal wine, initially soft but increasingly flavorful later on. Tuong Han commented that Ton Le is "a good person, and also good at acting".
Director Zheng Xiaolong commented that the actress is a person who is "the stronger she meets opponents, the stronger she becomes, not easily giving up".
For Ton Le, meticulousness can put pressure on her co-stars, but it is also a factor that helps her maintain her acting quality and create memorable characters on screen.
