用方言写的小说如果反映了说此种方言的人的生活，就会引起强烈的共鸣，而把一般小说译成方言则是徒劳无益的。对于那些不知道某种方言口语的人来说，刻意描写此种方言口语的文学往往特别枯燥乏味，因为他们无从捕捉赋予此种口语以生命的各种语音语调特征。

“At 1 pm yesterday afternoon, we saved a kid who had stayed in hunger for three days and was nearly in the state of prostration. When he saw us,his eyes were full of tears. At that moment, we felt that the trip and all our efforts are worthwhile.”Mr. Xu Lijun, the Captain of Ramunion rescue team said. When they found the kid, the team members handed food and water to him at thefirst time.

In recent years, the Ramunion rescue team has travelled abroad for many times and participated in transnational earthquake rescue missions in Nepal, Pakistan, Ecuador, Italy and Indonesia. In July 2018, the Ramunion rescue team took part in the marine casualty rescue work in Phuket of Thailand.
