1, you can't find the address of these video materials, or you can't download them after you find them?

I suggest you search from Baidu (mp3) and enter "fire fighting" or "safety training" to find it. Click to download and save.

3. Or you can play these videos directly on some websites, and then look for them in the web cache (that is, temporary Internet folders) (generally sorted by size, these files are larger and easier to find).
