This is a pair of "missing words", and the missing words are clear at a glance. For example, the first part should be "filial piety, faithfulness, courtesy, honesty and shame", and the word "shame" is "shameless" without it. The bottom line is that "1234567" is missing an "eight", which means "forget eight"! So this couplet is cursing "Inglourious Basterds". If you are satisfied, adopt it!
