In the original article, we neglected to include the funder “Social Science Planning Foundation of Anhui Province, AHSKYG2017D138” to “Yongjun Zhang.”
A correction has therefore been made to the Acknowledgement statement:
“This work was supported by grants from the Humanities and Social Science Research Foundation of Education Department of Anhui Province (SK2015JD11), the General Project of Humanities and Social Sciences of the Ministry of Education in China (13YJC740112), and the Social Science Planning Foundation of Anhui Province, AHSKYG2017D138. We thank Yamikani Ndasauka for his suggestions during the proofreading of this paper.”
Additionally, in the published article, there was an error in affiliation “1 and 2.” Instead of “1 School of Foreign Languages, Anhui Jianzhu University, Hefei, China” and “2 Center for Biomedical Engineering, School of Information Science and Technology, University of Science and Technology of China, Hefei, China,” it should be “1 Center for Biomedical Engineering, School of Information Science and Technology, University of Science and Technology of China, Hefei, China” and “2 School of Foreign Languages, Anhui Jianzhu University, Hefei, China.”
The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
