Preface: 4th International Workshop on Education Reform and Social Sciences (ERSS 2021)

This proceeding includes original and peer-reviewed research papers from the 4th International Workshop on Education Reform and Social Sciences (ERSS 2021), held from November 27-28, 2021 in Chengdu City, China.   The aim of ERSS 2021 is to provide a platform for educators, scholars, managers and graduate students from different cultural backgrounds to present and discuss research, developments and innovations in the fields of Education Reform & Social Science. It provides opportunities for the delegates to exchange new ideas and application experiences, to establish business or research relations and to find global partners for future collaboration.   ERSS 2021 received 147 manuscripts. And 53 submissions had been accepted by our reviewers. By submitting a paper to ERSS 2021, the authors agreed to the review process and understood that papers undergo a peer-review process. Manuscripts were reviewed by appropriately qualified experts in the field selected by the Conference Committee, who gave detailed comments and-if the submission was accepted the authors would submit a revised version that considered this feedback. All papers were reviewed using a double-blind review process: authors declared their names and affiliations in the manuscript for the reviewers to see, but reviewers did not know each other’s identities, nor did the authors receive information about who had reviewed their manuscript. The Committees of ERSS 2021 invested great efforts in reviewing the papers submitted to the conference and organizing the sessions to enable the participants to gain maximum benefit.   With our warmest regards,   Yang Zhou Pin Wang Qi Xia   Conference Organizing Committees
