Red rose and white rose paper
In recent years, so many publishing houses have published Zhang Ailing's collected works, including her novels, and of course this red rose and white rose. This can't answer your question. There are many kinds of electronic versions. People who make e-books do not enter the text according to the original page number, so it is difficult to know and guess "which page is from the novel", and so is Lu Xun's "Regret for the Past".
