However, Feng Jinhu from the press center for Microsoft China toldYouth Weekendthat the "I'm" project is only for Messenger users in the United States. Instant messages sent by Chinese users would not count. This has not affected Chinese Messenger users' interest in the little green symbol. These users hope their instant messages will actually contribute to charitable organizations someday. From the passage, we can come to a conclusion that   _  .
