Almost everyone was moved to cry by a lot of sad or moving stories. During the performances, they donated money to the disaster areas(灾区). The show was so successful.

Besides that, many other stars are doing things for disaster areas in many ways. Kungfu star Jackie Chan and the foundation(基金) named Hong Kong Emperor Group have together donated 10 million yuan. And he also sent his consolation(安慰) to the people in the disaster areas and encouraged them to hold on because “People all over the country are with you.” Xiao Ke, a songwriter, wrote and recorded a song “I Know You Will Come” to warm the hearts of the people in despair(绝望). CCTV’s top show “The Same Song” also held a charity special to help them.
