Wang LingJiao used the chance to scramble out. She took out a cylinder of fire-light from her lapels and shook it a few times. A light shot out of the cylinder. Along with a sharp whistle, it rushed out of the wooden window and exploded in the sky outside. Then, she fumbled out a second one, a third one. Hair tangled, she mumbled, “Come… Come… Come here… Everyone, come here!” Through the pain, Wei WuXian pushed Jiang Cheng, “Stop her from sending any more signals!” Jiang Cheng let go of Wei WuXian and lunged in the direction of Wang LingJiao. Yet, at the same time, Wen ZhuLiu was closing in on Madam Yu. He looked as if he was about to knock her down. Jiang Cheng hurried, “Mom!” He immediately gave up on Wang LingJiao and threw himself over. Wen ZhuLiu didn’t even turn his head as he struck, “Not even close!” Jiang Cheng’s shoulder suffered the attack. Blood immediately burst from his mouth. Wang LingJiao had already let out all of the signal fire-lights. Sharp whistles and bright sparks filled the entire grey-blue sky. - Chapter 58, EXR

It's quite interesting how, in this moment, Jiang Cheng does exactly what he's always criticised Wei Wuxian of doing: endangering the Yunmeng Jiang sect by 'playing the hero'. That's not what either of them are doing, of course – it isn't a motivation for Jiang Cheng here, it's not a motivation for Wei Wuxian anytime else, and the motivations they have definitely make sense – but it's exactly the sort of behaviour Jiang Cheng would criticise Wei Wuxian for, with those exact words.

Yet, no character ever criticises him for this – Wei Wuxian doesn't, even when it was his (necessary) advice that was disregarded; Madam Yu doesn't, even when her sect suffered as a consequence. Even when it very likely played a role in Lotus Pier's downfall (at least in getting a lot of Wen sect cultivators to get there very fast), it's never brought up by any character ever again... whereas Wei Wuxian's action of saving Lan Wangji, Jin Zixuan and Mianmian in the Xuanwu cave constantly is, even when the Wen sect was pretty certainly going to attack Lotus Pier anyway*. That's not to say Jiang Cheng should be blamed for the fall of Lotus Pier, either – that's on the Wen sect, and regardless of both of their actions, the attack was probably going to be a success. And can we blame someone for making a panicked decision protect his mother? – but one's action is definitely more direct than the other, and it's not the one that's constantly blamed.

The aim, though, isn't to compare the actions so much as the attitudes of the people involved, and this is another little detail that shows the imbalance in Wei Wuxian and Jiang Cheng's dynamic. Again, Wei Wuxian doesn't say anything about this afterwards, and doesn't seem to blame him, even when it's his words that were disregarded, and when the Jiang sect and Lotus Pier were undoubtedly very important to him as well. Which is good! That's a good thing and definitely the healthier option for both of them! If the roles were flipped, and Wei Wuxian saved a(n admittedly non-Yu Ziyuan) person, disregarding Jiang Cheng's orders while leading to more danger falling on Lotus Pier? Jiang Cheng would never stop blaming him or bringing it up. Even after the many years that passed between then and Wei Wuxian's resurrection, he still blames Wei Wuxian for the fall of Lotus Pier due to his actions in the Xuanwu cave** – once again, a much less direct scenario.

*Very strategic location (trade hub etc), they attacked the Cloud Recesses already, Jiang Cheng's internal narration literally admits this:

In his heart, Jiang Cheng knew clearly that back in the cave of the Xuanwu of Slaughter at Dusk-Creek Mountain, even if Wei WuXian hadn’t saved Lan WangJi, the Wen Sect would have found some reason to come over sooner or later. But he had always felt that, if the whole thing with Wei WuXian didn’t happen, maybe it wouldn’t have been so soon, maybe there would’ve been some way to turn things around - Chapter 59, EXR

Yet there was some time between the end of the Wen indoctrination and the Fall of Lotus Pier, and we never even saw attempts at security adjustments!

**As we see in the Ancestral Hall:

Jiang Cheng mocked, “Look how forgetful you are. What does unwelcome people mean? Then let me remind you. It was because you played the hero and saved Second Young Master Lan, who’s standing beside you right now, that the entire Lotus Pier and my parents went down with you." - Chapter 87, EXR
