Old Chinese Scrolls - Large

2 long Chinese scrolls with landscape scene.  First one with  grey craggy mountains (Yellow Mountain in China?) and blue and orange pagoda structures (1st 3 pictures).  And the 2nd one is one with green mountains and orange and grey pagodas (2nd 3 pictures)  Very dramatic landscape scene.  Purchase in China either in the mid-late 70s or early 80s. The outside paper has some spotted discoloring showing age but the actual print itself is in excellent condition.   Thanks.
