The part that I'm taking on isn't exactly clear at the moment. I know I will be one of the ensemble..and possibly get a few lines here and there....The show already has it's lead roles casted and the other roles are not suitable for my age. But, I don't mind...it will be the first time that I actually get to be a part of a professional Broadway production! Everything is coming from NY!!! And the original writer is going to be the director! So, I know that this will be my chance to learn and make my way into the industry. Hopefully, next time, there will be a bigger role for me to play.I'm so thankful that God has been leading me into the right direction. I am so blessed with opportunities...and I know that my patience is finally paying off. I'm very excited to be able to train more in tap dancing because I have always wanted to improve in that area....it's going to be a lot of hard work..but, I'm so looking forward to it. I do feel very sorry for my fans who have been walking with me since the beginning of the competition. They have been so supportive of me and it made me so sad to see them cry when I made my decision. I hope that they will not be upset with me because of it. I hope that they will see that this choice will only help my future...and I hope that they will continue to support me even though my participation with the competition has come to an end. It really touched me to see that they cared so much.

我知道我可能只是其中一个群舞，或许会有点台词，因为他们早就订了女主角人选，另一个女角年纪比较大，并不合适我，但是我不在乎…这是我的第一次参于真正百老制作的演出，每一个成员都是从纽约来的，原编剧将会亲自来导演这次演出，所以我很清楚这是我最好的学习机会，也是给我提供了一条通向百老的捷径之路，下一次我一定会争取到一个很好的角色…我感激我的上帝指引我一个正确的方向，我非常感激有这麼好的一个机会，我等了那麼久，总算有了一个好的起步…我特别兴奋的是，我这下子总算有机会好好学"踢躂舞"了，这是我最弱的一种舞，我一直希望能把它学好，尽管我知道会很辛苦，但是我已经作好了思想准备…还有对那些从一开始就支持我的那些粉丝，我感到非常抱歉，尤其是当我在台上说出我离去的决心时，看到她们一个个都哭得那麼伤心，我也很难过，我希望她们能明白，这个决定是绝对对我前途有利的，我希望就算是我不再比赛，她们仍然会支持我，一直以来，她们对我的关心和鼓励最让我心动的…。

In order to research the spray of LPG/diesel mixed fuel, it is the first time that this work studied the atomization characteristics of LPG/diesel, including spray angle, droplet size distribution, mean diameter, typical diameter, diffusion degree and impenetrate distance by using a high spatial resolution digital camera.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
