On March 27, many Chinese stars gathered at the anniversary gala of the Xiaohongshu platform in China. The fact that Ngu Thu Han and Chuc Tu Dan had absolutely no interaction caused a stir, sparking discussions about changes in the relationship between the two.
When attending the event together, the two were caught not chatting even though they were standing close to each other, without eye contact, even when passing by, they did not greet each other.
After that, Ngu Thu Han posted photos taken with Luu Thi Thi and Luc Kha Nhien, but without Chuc Tu Dan. Although at this event, only Chuc Tu Dan was the only one in the cast who had collaborated and had a very good relationship with Ngu Thu Han.
In 2024, the two actresses who co-starred in the movie "Vĩnh dạ tinh hà" became close sisters both in film and in real life.


Chuc Tu Dan once revealed that she had added some close gestures to the character Lang Dieu Dieu (played by Ngu Thu Han) to the film script because she felt Ngu Thu Han was too lovely.
Movie fans named it "The Four Heroes of the Bamboo Forest" to refer to the close relationship between 4 actors in "The Starry Night" including Esther Yu, Julian Chuc, Dylan Dinh and Michael Yang.
In the sideline promotion activities and filming of the "Shining Star" program afterwards, the actors were also extremely comfortable, like family members.
When participating in the program "Billion Dollar Riding the Wind and Waves 2025", Chuc Tu Dan also publicly called to ask Ngu Thu Han about stage skills.
However, in September last year, the relationship between the two became the focus of discussion when Chuc Tu Dan was discovered using her personal Weibo account to "like" a controversial video titled "The incomprehensible actions of Ngu Thu Han", content associated with controversies and negative images of the actress.
At that time, Esther Yu was entangled in a storm of criticism surrounding the noise related to personality and family business activities.
In just 3 hours after her actions caused a stir, Chuc Tu Dan apologized and explained. She said: "I really want to chop off my hand. I keep slipping my hand. I don't hate anyone. Sorry! Later I will pay attention, definitely use a secondary account to watch videos".
However, netizens suspect her motives, because the saying "using a secondary account" is understood as admitting to intentionally following negative content about Ngu Thu Han.
In addition, viewers also dug up similar "accidents" of Chúc Tự Đan before, she seemed to have "liked" a controversial content related to Tống Tổ Nhi, thereby questioning the actress's behavior habits.
After the incident, all public interactions between Ngu Thu Han and Chuc Tu Dan almost completely ended. From being close sisters, they became strangers, and the "no communication" at the same event this time is considered a public sign of a rift in the relationship.
