You should make a swap partition at first.

Yes, I already have a swap partition.

What is next step?

What about swap partition size? Where is it? SSD?

990MB, yes it is SSD.

I set it 2G, on HDD instead of SDD. The physical memory is 8G.
I can hibernate my Deepin computer every day.
Don't forget to be sure that fstab and grub.cfg contain swap partition.

990MB SWAP is too little,may cause an error. If you need to use the sleep function,it is recommended that the size of SWAP is equal to that of memory,at least 50% of memory size.
If you don't need dormancy function,then 0.5GB can.
990MB交换分区太小，可能会出现错误。若需要使用休眠功能，建议交换分区的大小与内存相等，至少是内存的50%。
如果不需要休眠功能，那么0.5GB即可。

Okay, but after resize my swap partition, what I need do to enable hibernation? Or Deepin will automatically enable it when my swap is the right size?

Deepin is enabled by default this function.Click "Suspend" button, equivalent to sleep.SWAP partitions need manual adjustment. If you want to achieve the Windows dormancy function, then sorry, deepin temporarily does not support.
deepin默认启用此功能。点击“Suspend”等同于睡眠。SWAP分区需要手工调整。如果你是想实现Windows的休眠功能，那么抱歉，deepin暂不支持。

1.uswsusp(recommanded)
2.swap+manually modify boot up hook+systemctl

Okay, Thanks!

Disable kernel nouveau is work for me
