Yes, it can be quite challenging for Chinese people to communicate with those from other countries. The biggest issue is the language barrier. Not everyone is fluent in English or other international languages, which makes it hard to express ideas clearly. Also, there are cultural differences that might lead to misunderstandings. For example, the way emotions are expressed or the importance of certain gestures can vary widely, which might confuse people from different backgrounds.

No, it's not particularly difficult for Chinese people to communicate with others globally. Many in China start learning English at a young age, which greatly reduces the language barrier. Moreover, advancements in technology have made translation tools readily available, facilitating smoother communication. Also, due to globalization, there's a greater understanding of different cultures, which helps in reducing misunderstandings.

It really depends on several factors. For someone from a major Chinese city who has received a good education and perhaps studied abroad, communicating with foreigners might not be too difficult. However, for someone from a rural area without much exposure to other languages or cultures, it could be quite challenging. Also, younger people who have grown up in a more globalized world are likely to find it easier than older generations.
