Didn't know 老李 has a youtube sub-channel, this video happened to appear on the recommended feed. Singaporean Chinese here, my written Chinese isn't good, so had to type in English. Thank you for sharing your thoughts and what is happening at the back which we all don't get to see. I always thought most Chinese (regardless where they are from, China, Taiwan, Malaysia, Singapore) would have the same values, principles and moral compass. Your sharing gave us some insights on how some ingrate mainland Chinese behaves and how ungrateful and unappreciative they are towards your kindness and patience. It sets me to rethink and re-evaluate how I should feel towards some of them.
