致谢 Acknowledgments

The creation of this work EverFlow Mandarin—An Intermediate-Advanced Level OER Chinese Textbook was supported by Open CU Boulder 2023-2024, a grant funded by the Colorado Department of Higher Education with additional support from the CU Office of the President, CU Office of Academic Affairs, CU Boulder Office of the Provost, and CU Boulder University Libraries. In particular, we wish to extend our gratitude to Melissa Cantrell, Caroline Sinkinson, and Merinda McLure, who serve as OER leads for this grant. Whenever we have questions about copyright and licensing, they consistently provide us with precise and clear guidance.  

We are also deeply grateful to Du Chinese, That’s Mandarin, and GoEast Mandarin teams. There are 35 texts in this textbook are selected and adapted from their work. In support of our project, they have graciously licensed these texts under the CC BY-NC-SA 4.0 license, ensuring free access for users of our textbook. In addition, we want to express special thanks to Lily Ng, the marketing director of Du Chinese, and to Peter and Yueyuan, the co-founders of Du Chinese. This collaboration has been made possible through their patience, expertise, and unwavering support.   

Furthermore, we would like to recognize the contributions of Wilson Seet, whose assistance was invaluable in constructing the website for our textbook. We also want to thank the Web Express team of the University of Colorado Boulder for their guidance in publishing this textbook online.

Last but not least, we are thankful to Professor Xi Ma of the University of Washington. At the outset of this project, she provided us with insightful suggestions drawn from her teaching experience and expertise in creating online open educational resources.

We are deeply grateful to everyone who has played a part in making this project a reality. The creation of this textbook is a result of teamwork. We extend our heartfelt thanks to all of you.
