最终还是不得不发出这样的邮件
Dear Arthur I am sorry to say that i would like to commit a resignment. Since I can't involve citi well and can't bring too much value to citi, in order to avoid to waste unnecessary resources, I have to commit this resignment. It's a hard decision to make, but at last this is my final decision, I hope you can understand me for this. Hope you and the whole team can achieve great success in the future. Rgds Darren Wang
