In the 20 13 era, Li Dan, a model who looks like Yang Mi and goes in and out of Aurors Medical Beauty Institution, became the spokesperson of the new dimension breast enhancement brand of the institution, and held a signing ceremony in Beijing. On the day of the event, Li Dan, wearing a lace perspective dress, successfully attracted the attention of the live media as soon as she appeared. Through this new dimension, she rose from an A cup to an E cup. It also proves that she is indeed the best candidate for brand spokesperson. At the press conference, Li Dan not only talked about her drama cooperation opportunities with New Dimension, but also revealed her next work plan to enter the film and television industry.

When talking about becoming the spokesperson of plastic surgery institutions, Li Dan said with a smile that it was very dramatic. It turned out that when she went in and out of plastic surgery institutions, she was mistaken for Yang Mi by the media, so the Hong Kong media published a report entitled "Suspected actress Yang Mi went in and out of plastic surgery institutions", which caused an uproar for a while. In order to avoid implicating Yang Mi, Li Dan has clarified the matter in time. At the signing ceremony, Xinyuan Brand said that through this oolong report, they found that Li Dan was very suitable as a brand spokesperson, not only because she resembled Yang Mi's appearance, but also because she saw her efforts for her career and her development potential. Later, Li Dan told the media that the reason why he chose to wear a transparent dress today was to better show the postoperative effect.
