Although Crystal is slim now, with a small face and big eyes, it took him two years to lose weight. In 2009, when I was filming a short play with another "national husband" professor, Kim Soo Hyun, I had a round face and a lovely fleshy figure, but I didn't have the characteristics of becoming a popular female star at all.

Netease Entertainment once interviewed her and decided to embark on the road of performing arts. After that, Crystal began a long slimming plan. She did not choose the extreme way of fasting to lose weight, nor did she seek the secret recipe for losing weight. Instead, she adopted the most stupid method: long-term dieting and exercise, which requires perseverance most.

Crystal's diet is also simple and rude. She only eats boiled tomatoes and cucumbers every day. A year later, she successfully reduced her weight to double digits. After that, she added eggs to her diet and persisted for another year. It is also unambiguous to start exercising, and it is completely difficult for her to perform one difficult movement after another.

If you lose weight, you will not be red, but you will have no money. At that time, Crystal also did what internet celebrities are doing: opening an online shop. Not only as a model, but also as a customer service, I will reply to buyers' comments, and it is also very hard to make money. It is said that in her early years, she told people that acting was not as good as selling clothes to earn more money, but she still wanted to be an actress, so she worked hard to hone her acting skills in various crews and finally seized the opportunity to portray the image of "Crown Princess" very well and became famous overnight.
