How to tell the difference between Past Perfect Continuous and Past Continuous as they both show the process in the past?

Past Continuous Tense is used to express interrupted actions in the past. The tense shows that a longer action is interrupted by a shorter action in the past. While they were walking on the street, they saw a stray skinny cat. /делал что-то, что было прервано другим действием/

Past Perfect Continuous Tense is used to express a past action which started in the past and continued (and we know how long the action had continued) till another action or time in the past.
