Since your Microsoft Office information is stored in the Windows Registry and is thus difficult to copy for correct operation, specialized application migration tools have arisen. With an Office mover software, you can easily transfer your Office installation to an external hard drive.

It can transfer Microsoft Office to an external hard drive via the “Application Migration” mode, which will change Office's installation location. In addition, if you've forgotten your Microsoft Office product key, Todo PCTrans can find it with a single click.

Translating English to Chinese refers to the process of converting English text into Chinese. This could involve translating sentences, paragraphs, or entire documents. For instance: "Hello, how are you?" translates to "你好,你怎么样?" in Chinese. "Actions speak louder than words." translates to "行动胜于言语" in Chinese. In practical applications, this often requires a deep understanding of the grammar, vocabulary, and cultural context of both languages to ensure accuracy and appropriateness in the translation. Nowadays, there are also many online translation tools, such as Google Translate or Baidu Translate, that can help people quickly translate from English to Chinese. However, these may not always capture the full context and emotional nuances of the original text.

Chinese: 那只敏捷的棕色狐狸跳过懒狗。 If you have specific English content that needs translation, please provide it, and I'll assist you with the Chinese translation.
