Man these people people aren't familiar to Chinese people especially from close. The same thing i witnessed for example at an well known youtuber (bald and bankrupt) videotrip in Xinjiang who did took a regular passenger train. People were treating him like an alien but not in an offensive way. It was so funny and lovely too.
is there actually a video of these kids calling him ching chong? because if there isn't then I call BS on this story. very few in the Arab world know the term "chingchong". and literaly no one knows the term "chink". if they were to call him something, I would expect them to call him "Jackie Chan" or something similar.
to be honest if a person who claims to be a humanitarian worker get's this much hurt because some kids called him a name then he is not cut for the job. a while ago one of my colleagues brought her daughter to work. the daughter started giving nicknames to us based on vegetables so cucumber, tomato, she calls another colleague eggplant because he is dark skinned, obciously the mother tells her not to say that. it's just a kid. it's not like the kid told you "go die".
What has China done for Gaza? Has China helped Iran or supported UN sanctions? China has given both of them lots of verbal support, but when it comes to actions, there's a lot of empty promises like first loudly claiming big investment numbers and then pulling out of projects in Iran at the request of the US
to be honest demanding that the Palestinians be grateful to any one is completely out of touch.
the entire world (including China and Russia) abandoned Palestine and decided to just sit back and watch one of the most brutal genocides in modern history. the world chose to do nothing because they realize that Israel is America's holy master. for America.. Israel and it's people are much more important than America and it's people. if you harm the US directly then the American retaliation against you will be less severe than if you would hurt Israel. after all America chose to forgive Joulani & AlQaeda, the organization that killed 3000 American civilians on US soil because Joulani promised to befriend Israel.
if any Palestinian choses to be grateful to those who didn't help his people then that Palestinian has no self respect. the only ones who the Palestinians are probably grateful to are the Yemenis and maybe to a less extent Hezbolah and Iran. and even for these countries I'm sure you could still find the occaional Palestinian wahabi who doesn't give a fk about the Palestinian cause and only cares about killing the "kafir Shia".
to be honest people demanding that Palestinians be grateful to China or any other country is even more out of touch than J.D. Vance telling Zelensky "you didn't say thank you".
