I don't know what to say other than you don't understand what I wrote.
1. When you connecting your mikrotik to the dlink, it does get a dynamic IP 192.168.1.x via DHCP. That means your mikrotik had a static IP 192.168.88.1 & a dynamic IP 192.168.1.x.
2. The reason why your clients on mikrotik side can connect to the 192.168.1.x range is because the connection NAT by mikrotik router. That means your mikrotik will connect to the server on 192.168.88.x client behalf and the originating connection IP will be masqueraded as 192.168.1.x IP of the mikrotik. The server will see the connections is made by mikrotik's 192.168.1.x & not by 192.168.88.x.
3. The clients on dlink side cannot connect to 192.168.88.x because there is no route to that subnet. The dlink router will have to route it somewhere or else it will use the default route to the internet which in this case will not work. That's why it will have to route it to mikrotik but mikrotik will need a static 192.168.1.x IP or else the route won't work if the IP changed.
4. And mikrotik by default (if you use quickset) will have firewall filter rules to drop incoming connections from the WAN port, that you will have to disable or else you still cannot connect from 192.168.1.x to 192.168.88.x.
5. Stop trying to justify your network decision what so ever. I never questioned it & it has nothing to do with your problem nor my answer.
Ya don't understand you. can you simplify it please.
I just want my client in 192.168.1.xx to be able to connected to the 192.168.88.xx
so referring to your guide i should have 192.168.1.xx ip on MT router as well ? MT router to have both .1.xx and .88.xx IP ? for this part can Master jio enlighten. and then needed to check on the firewall rules for MT router side right.
btw Master Jio it is not my network decision, my management need it to have it two different subnet. If for me all under single subnet would not have such hassle.
appreciate you masterly skill and advise
