Rainie Yan celebrates at the after party and was super high. Using "Lian Grandpa, you came back" voice, she recited the what her mother commend her as "the stage's lively spirit" through text message. As for why her mother is being so low-key and didn't show up, Rainie said if she was holding a booking concert, her mother could put on a Chinese dress and officially declare a position!
Having put on two concerts, Rainie expressed that she hopes her next album will have some dance songs, letting people wonder whether or not she's trying to compete with Jolin? She said that the two have different music tastes, and she hopes that she will have a favorable type of beauty, and will only unfold "up to" a certain sexy flavor.
Good friend Mike He, Pei Lin all went to congratulate her A-Ya and Ariel Lin cheered her on through the telephone. In Beijing, Jackie Wu through transocedanic telephone taught her for 5 minutes, telling her to not be nervous and to have fun.
Rainie is currently super popular, the jeans merchant offered 2,500,000 to invite her to speak as their spokesperson, and the sale prices soared 3 times compared to what they were a year ago. They didn't think that in her new wardrobe, with the fact that she doesn't have enough courage to wear mini skirts, but because of the salary, Rainie put on a brave face and wore the miniskirt - and realized that showing her legs isn't a bad thing either.
On Saturday, she finished her concert in Taichong, and she immediately rushed back to Taipei to do a show for the jean company. When she was changing with a bunch of models, she originally wanted to sneak peak at the models changing, but then she realized that the backstage showed 10 cms of space, so she changed and worried about paparazzi instead.
