(1) This play is adapted from the Tibetan folk stories compiled by Comrade Xiao Chongsu.I would like to pay tribute to Comrade Xiao Chongsu! (2) Because I am not very familiar with the ancient and modern customs of Tibet, the local color is not emphasized in the play.Tibet can be used as the background during the rehearsal, or it can be placed in other places.The characters are all anonymous, and can be added if necessary. (3) There are some discrepancies in plot between the script and the story compiled by Comrade Xiao Chongsu: 1.In the original story, the three sisters are all the daughters of the headman. In the script, the third sister is changed to be a righteous daughter so that it is more suitable for marrying the frog rider.

2.In the original story, the frog skin was burned by the third sister, but in the play it was robbed by the headman, and there were many conflicts. 3.The biggest change is the ending of the story.It turned out that the frog rider died, and the third sister turned into a stone in front of his grave.In the age when the story was formed, such an ending was very natural.When I adapted it, I turned the tragedy into a comedy. The frog rider was dying and was rescued by the third sister. 4.In addition, there are some other minor changes, all for the purpose of making the story more concentrated and the characters more distinct, that is, I will not explain them one by one.

(4) The full text of the script is composed of rhymed libretto, without bluntness.If it is too much, some part of the libretto can be changed to recitative, but I hope to be able to recite the original rhyme, do not change it to prose, because reciting rhyme can be accompanied by music, and the atmosphere is better. (5) The frog rider can be played by two people, the first half is baritone and the second half is tenor.The first half has a curved face, green face, golden eyes and wide mouth, and the second half is handsome.
