Local language communities are of great importance for linguistic research, as members provide words, phrases, and even entire stories in the language that is being documented or studied. To give back to the local community, copies of this book and the accompanying cd were given as a present to local language consultants in Mianning, Sichuan Province, People's Republic of China, in November 2017, as a token of appreciation for their help in the creation of this book. Here and here are pictures of the ceremony, organized by professor Wang Dehe of Xichang College.
