Brief Summary
The fight against the spread of the 2019-nCoV epidemic has achieved some success in China, but the epidemic is far from over. A key factor making the epidemic under control in China is the government's call for social distance, which has led to few people going out for donation. As a result, the number of blood donors on the streets has been continuing to decline. The first urgent recruitment of blood donors had been implemented during the period from 30 April to 10 May via emergency recruitment SMS . This repeat trial has been designed to further confirm the results from the the first recruitment by comparing which information extraction frameworks would be more sensitive to blood donors in emergency situations.

Interventions
The literature shows that the information extraction and processing in emergency is different from the normal situation. To find the most effective emergency recruitment method during an outbreak, we intervened with a well-balanced group of donors by presenting different emergency recruitment text messages.
