PrevReview MC4.1 BE1.4 BE1.5 CT CE

This is a combined software. One software can run multiple tools at the same time. The reason why there are two BEs is that BE1.5 searches quickly but is error-prone, but BE1.4 searches slowly but is not error-prone, so everyone should use it rationally. Use 1.5 to search and then use 1.4 to modify. I saw this on other websites a few days ago. Because there was an error during the installation of my mobile phone, I don't know what happened. I just remembered it now and posted it for everyone to take a look!
