No bro u r wrong lololol don't compare this to 'real' tradition and culture. She only came looking for trouble and she is only using the kite as an excuse.
Plus sth can be considered disrespectful if it's done in ur country/region. Like ur example, cows are respected in India but they are just food/ meat in other countries. But is eating them as food in other countries disrespecting Indian culture. No.
But here she entered jiang sect which is not even her sect. So yeah she is being petty.
It's literally a red circle on a piece of paper and not an actual stylized sun. She looking to stir up trouble, WRH wanted either subjugation or annihilation and used any and every excuse. And even if it was, absolutely no right to wipe out an entire group of people. It said before and I'll say it again, there was a massive problem and the Sect's did little against it until something like the Fall of Lotus Pier to make everyone accept that WRH needed to be stopped long before not that they learned anything with the LanLing Jin.
Understandable, the YunMeng Jiang Sect especially are very skilled archers that use kites as a part of their training regime. You're not dumb. I wasn't criticising, just pointing out that the insult wasn't actually one and she was only there to create an open for an attack, given that two weeks had past and nothing was done immediately (aside from WRH mustering his forces) about Wei Ying supposed distracting that dog Chao.
I just don't understand how can they be so freaking petty?! It's just a kite with a red circle
