I heard Sierra no more support HFS standard format but My MacBook Air 2014 and MacBook 2017 are able to mount a disc was formatted HFS Standard. Any info for the issue? My both computers are installed 10.12.6.
MacBook (Retina,12-inch,2017), macOS Sierra (10.12.6)

NO. I was just pointing to documentation on the Mac that specifies that standard HFS is supported.
All those GUI features often times are using command line features under the covers. Since the GUI does not come with a lot of documentation, you can often times find out useful information by looking at the command line 'man' pages for commands that perform similar functions to what the GUI does.
That is all that I did. I looked at the man pages for the command line equivalents to the GUI operations.
If you attach a standard HFS formatted disk, or double-click on a standard HFS formatted .dmg, it will mount just like an HFS+ or FAT, or exFAT, or NTFS, etc...

See Applications -> Utilities -> Terminal -> man mount_hfs
...
mount_hfs -- mount an HFS/HFS+ file system ...
So the mount command can handle HFS and HFS+ file systems.
But the Disk Utility GUI is not interested in creating plain HFS file systems. It just wants to create HFS+ with journaled file systems, or FAT and exFAT Windows file systems.
There are additional file system formats that the Terminal 'diskutil' command can create, but none of them are the standard HFS file formats.
What Disk Utility will create does not say anything about what macOS can mount and read and maybe write.
Sierra is fine with the standard HFS format. You may have read something about High Sierra - we are not allowed to discuss features that have not been made public by Apple - they will no doubt make an announcement when they release High Sierra.
Please provide a reference where you heard that.
