Head Canon that Interpeak relations in Cang Qiong mountain was bad until the Peak Lords witnessed the broship of Shen Qingqiu and Shang Qinghua
Before SQQ's qi deviation, the peak lords only communicate during meetings, and these meetings are mostly called by the then only transmigrator—SQH.
You think LQG and QQQ are close? No. They hate the same person but in different ways. They don't really talk about it together. MQF is a natural worrywart, but is not really friendly. Don't get me started with YQY, who is only irritatingly diplomatic (I get SJ's irritation tbh) but aloof.
Since the immortal alliance incident, the peak lords notice Shang Qinghua's often visitation to the grieving Shen Qingqiu. "What a nice martial brother." So they do the same, bringing SQQ gifts and kind words. Sometimes they catch one another in the Bamboo House, so SQH urges them to stay and have tea with Shen Shixiong. The more the merrier, he says. "What a good philosophy!"
Inevitably, they notice their deep friendship. How bizarre. None of them are friends on such a level. Maybe they should befriend neighboring peaks? An Ding and Qing Jing are geographically close, maybe that's why they're such besties.
During stuffy meetings, the two would giggle on their own musings, speaking the language they developed on their own (that's what besties do, right?). That alone would subtly break the tension.
When SQH leads the meeting, SQQ would raise his hand to insert unnecessary but funny quips, leading them to think that perhaps they can put fun in work.
When a peak lord is angry at something (like overwork or personal issues) SQH and SQQ would approach them after the meeting to ask them for more details. They hear them call it "bestie debriefing" or "juicy tea" whatever that is. Communicating with this peak lord in this way improves the situation more often than not. The angry peak lord (usually WQW or MQF) would also feel better for the attention.
The book always shows SQH and LQG visiting the bamboo house but not the other way around, so it looks like the Bamboo house has become a cafe of some sort. Other peak lords visit Shen Qingqiu to "check up on his emotional and physical constitution", and end up talking about books, beasts, rumors—anything fun, really. SQH now calls it the Bamboo Café, the others secretly and sappily calls it the House of Friends. (SQQ and SQH found out about it and they both cringed. But hey, they love their martial siblings)
