China DOS Union

I have a text whose contents are like this:
∥bc915∥∥∥Ediary 2.53∥59.117.162.144∥2007/08/23/ 01:10:07∥2007/08/23/ 01:10:07∥698∥4∥2007/10/12 13:13∥∥∥∥TATATA∥


The red parts are the parts I want to delete.
And I want to replace the blank parts with "China forever"
And I need to modify only the strings within that delimiter, and not modify anything else

But after writing this much I don't know how to continue

@echo off
for /f "delims=" %%f in ('dir /on/b "1.txt"') do (
for /f "tokens=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 delims=∥" %%i in (%%f) do echo %%i∥∥%%j∥%%k∥%%l∥%%m∥%%n∥%%o∥%%p∥∥∥∥%%q∥>>2.txt
)
pause

Could I trouble the experts to help me write an example
I'll modify it according to my needs
Many thanks ><"

Many thanks to the experts for helping
But I want to modify only the string inside %%p, and nothing else should be modified
But I just tried it, and it seems nothing got modified @@?
What is the reason?

sed "/∥/ s# #中國萬歲#4;s#/##7;s###7;s#:##5" 1.txt>2.txt

If you can use sed, why not use it??

Many thanks to expert terse for the guidance ^^
One day my teacher, a father for life @@

For expert abcd, it's not that I won't use it @@
It's because I want something I can "understand" and "learn"
Right now I only just know how to read DOS commands and have just started learning to write them
I'm learning bit by bit
Using sed can work successfully, but I haven't learned that part yet ^^
Many thanks for your guidance, and for understanding a beginner
