How to deal with the air leakage of sliding windows

When decorating, if there is a leak in the windows, this is the most troublesome thing. Especially for sliding windows, the sealing effect just after installation is still acceptable, but as the number of sliding times increases, the sealing effect of the window will deteriorate after a few years or even in some months. In this case, what should I do if the sliding window leaks?

If there is air leakage in these two places It's relatively easy. You only need to replace the special sealing strip, and it needs to be replaced multiple times over time. If it is the connection between the window frame and the wall, which is the first case, in addition to the more complicated solution above, it can also be solved by filling with glass glue.
