Dear Linh,

I hope this email finds you well. London is an incredible city with so much to offer. The weather here is quite unpredictable, as it often changes throughout the day. Sometimes it's sunny and warm, while other times it can be cloudy and rainy. It's advisable to always carry an umbrella with you.

On another note, I have managed to find a part-time job at a local cafe. It's been a great experience so far, allowing me to interact with locals and improve my English skills. The family I am staying with has been incredibly welcoming and kind. They have made me feel at home and have been helping me adjust to the new environment.

In the evenings, I often explore the city and visit various landmarks and attractions. London has a vibrant nightlife, and there are plenty of options for entertainment and socializing.

Regarding my English classes, they have been quite intensive and beneficial. The teachers are highly qualified and provide engaging lessons that focus on all aspects of language learning - speaking, listening, reading, and writing. I have already noticed improvement in my language skills, and I'm excited to continue learning and exploring this beautiful city.

Take care and keep in touch!

Best regards,
