The following information has been given:

Therefore TZ='Asia/Shanghai' will be used.
Selected time is now:	2018年 07月 14日 星期六 15:06:33 CST.
Universal Time is now:	2018年 07月 14日 星期六 07:06:33 UTC.
Is the above information OK?

You can make this change permanent for yourself by appending the line
	TZ='Asia/Shanghai'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Shanghai

让时区修改生效

sudo ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
