Quynh Kool caused controversy in the primetime movie Wind Across the Blue Sky
Quynh Kool's performance in the movie "Wind across the blue sky" received mixed opinions.

Currently, Quynh Kool is appearing in the movie "Gio ngang khoa khoi xanh", co-starring with actor To Dung.
She plays Truc Lam - a girl who once believed that love and marriage were all she needed to be happy. Lam married Toan (To Dung) - a practical, quiet, patriarchal man.
But then her husband's indifference, financial pressure and her own mother's excessive involvement made her marriage increasingly suffocating.
On forums, many viewers debated Quynh Kool’s acting. The actress’s lines and expressions were said to be forced and lacking in emotion.
Some people say that Quynh Kool’s appearance and face are very different from her previous roles. Many people even suspect that Quynh Kool had plastic surgery, making her face look stiff.
Sharing with reporters, Quynh Kool denied rumors of plastic surgery.
The actress revealed: "Many viewers say I look different from before. But actually it's because I gained weight. When I filmed Us 8 Years Later, I weighed 50kg, but now I weigh 57kg so my face is rounder. Sometimes I edit photos too much when posting them on social media so the audience says I had plastic surgery."

In the film, Truc Lam is a childish, naive wife. Situations such as her buying expensive clothes for her cat despite her husband's hard work, demanding her husband to buy expensive housewarming gifts for her best friend, or frequently leaving in anger... caused controversy among the audience.
Toan - Lam's marital relationship also causes many problems because of their opposite personalities and views.
Talking about working with To Dung, Quynh Kool said: "The first time I met him, I thought Mr. Dung was a difficult person. I said that looking at Mr. Dung, he looked exactly like the character Toan - a grumpy, frugal, patriarchal person. When acting with him, I found him to be professional and analyzed the character very well. There were parts where I lost my emotions, Mr. To Dung was the one who helped me balance it. Thanks to him, I was able to do my role well."
