Dear Friend,

Thank you for writing to me. I am glad to hear that your school is organizing an overseas study tour. It sounds like a great opportunity for students to learn about different cultures and broaden their horizons.

I think it's important for students to have the chance to experience new places and cultures in person. Such experiences can help them become more open-minded and tolerant of others, as well as develop an appreciation for diversity. Additionally, traveling abroad can give students a better understanding of global issues and the world at large.

In terms of safety concerns, I suggest that you ensure that all participants are aware of the local laws and customs before they depart on their trip. You should also make sure they are familiar with basic safety measures such as not traveling alone at night or carrying too much cash with them. Additionally, make sure that all participants have access to emergency contact numbers in case something unexpected happens during their travels.

I hope this information helps! Have a great time on your study tour!

Sincerely,
Li Hua
