 2. crawl 300K of 4M webpages from the urls
 3. get pure text and remove content len less than 1k,
-4. use langdetect to tell the lang of the pages,
-we finally get total 160K pages : 101K ja pages, 47K en pages, and 12K other lang pages
-5. random sample 16K from ja mc4, concat with all 16k pages to get lang_all.txt data
-6. random sample 10K from ja mc4, concat with ja 10k pages to get lang_ja.txt data
-7. tokenize all text with "cl-tohoku/bert-base-japanese"
-8. feed lang_all.txt to fasttext to get model_all.bin
-9. feed lang_ja.txt to fasttext to get model_ja.bin
+4. use langdetect to tell the lang of the pages, we finally get total 101K ja pages
+5. random sample from commoncrawl 202303 and use langdetect to find 101k ja pages
