What may be needed for our office staff is a more professional Microsoft office, not a non-professional WPS. Because I am used to the Microsoft office on the computer, of course, I hope that it can also be used on the mobile phone, which is convenient for mobile work. Microsoft released a new Office application for IOS and Android the day before yesterday. Of course, there were separate Word, Excel and PowerPoint applications before, but the three-in-one office application is much smaller than the single program. The key is free.
