Thanks for your advice. I downdloaded files by clicking the "download" button in https://github.com/tesseract-ocr/tessdata/blob/master/chi_sim.traineddata. And I moved the chi_sim.traineddata file to /usr/share/tesseract-ocr/4.00/tessdata/ , and checked the file (which size is 42.3MB) exactly there. But, I cannot use tesseract. As I said, I can use tesseract with the file downloaded by executing sudo apt install tesseract-ocr-chi-sim, but the data downloaded from Data files did not work. I cannot understand why it did not work.
