Why Indians critize Chinese on twitter?

Recently I've been more active on Xiaohongshu also known as Rednote. While I was enjoying and having conversation with native chinese people. Though they are friendly and welcoming but they've pointed out these things specifically... They always mentioned that "because Indian excel in english speaking and have access to foreign media, they bash chinese and compare with chinese to belittle us" reason why we aren't comfortable with them. Indians who are in trade with china have always betrayed them at time of payment, they never reply or email. Creating a bad image... And list goes on. But things take different turn when they told me Indians can apply for visa to come to china for studing or work but we, chinese, can't apply for indian visa. Why is this happening. What y'all think? They really wanna know why Indians critize Chinese or anything related to china. While India is not even half of what china has developed...
