China's research vessel and icebreaker Xuelong, or Snow Dragon, has been trapped in deep ice after a helicopter from the ship rescued all 52 passengers aboard a Russian vessel stranded in Antarctica on Thursday. Chinese have taken to social media to voice support and best wishes. Here are some of their comments:

Lihaizhiying:Xuelonghas offered international humanitarian assistance, which can help build China's soft power. May Xuelong return safe and sound!

Kunanchengjiuxingfudefabao:There's nothing embarrassing about Xuelong awaiting rescue after rescuing others. Unexpected things happen in extreme Antarctic weather.

The Seventh Day of Jesus Christ:Our country did the right thing, sacrificing its research projects to rescue others. What our country has done has greater value.
