Hi Quoc,
If now I write 5 things to my friend to do and I write as follows:
This is the second time I have mentioned these things to you. I have also told these things to you directly but you haven't shown me any of your opinions. Now please do these things right now. (1)
Please correct (1)
(tenses, The tenses are OK.
words...) As a contrast to 'mentioned', I wouldn't say 'told directly'. I might say ' I have also discussed these things with you explicitly'. When you 'tell' someone something, you are not clearly asking for their opinion, but when you 'discuss' something, you are.
Also, you don't 'show' someone your opinions. You might say you' explain them', or 'make them clear', or 'express them'.
Finally, when you order someone to Now please do these things right now, it does not sound like you are interested in their opinions at all.
Best wishes, Clive
