Xu could be transLated to Xu in English, as it is a Chinese surname that doesn't have a direct English equivalent. If this is a specific person's name, it would be more accurate to use their official English name or transliteration if avaiLable. Wei can be translated as 魏 or 韦 in Chinese surnames. However, without specific context or additional information about the person you are referring to, it's not possible to provide a precise translation into English. In some cases, the surname Wei may be translated as Wei in English, especially when referring to a person who uses that surname in their official English name or is widely recognized by that translation. If you have more information about the specific person you are inquiring about, please provide it, and I will try my best to assist you.jie
