I need to write a letter to a friend who is moving to a new city. Can you help me with a draft? The letter should be friendly and encouraging, and it should include at least 3 bullet points of advice for their new life in the city. Also, the letter must contain exactly 4 placeholders represented by square brackets, such as [city name], [job title], [hobbies], and [weather]. Make sure to highlight at least 2 sections in your answer with markdown, i.e. *highlighted section*.
