The following information has been given:

    China
    Beijing Time

Therefore TZ='Asia/Shanghai' will be used.
Local time is now:  Tue Oct  9 10:37:00 CST 2018.
Universal Time is now:  Tue Oct  9 02:37:00 UTC 2018.
Is the above information OK?
1) Yes
2) No
#? Yes

Please enter a number in range.
#? 1

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

按照提示进行选择时区,然后:
root@B-OPS-75-1:~# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
root@B-OPS-75-1:~# apt install ntpdate –y
root@B-OPS-75-1:~#  ntpdate cn.pool.ntp.org             

cn.pool.ntp.org是位于中国的公共NTP服务器地址
