假如你是林涛，你的表哥 Alan 出生在美国。近期，他的父母准备带他回中国探望家人，Alan 发邮件提到，他想顺便游览中国的各大城市，并征求你的建议。请你阅读并回复邮件。
Dear Lin Tao,
How's everything? I'm so excited that Mom and Dad are finally taking me to China this summer! We'll visit our family in Fujian, but I've begged them to let me explore more cities—such as Nanjing, Luoyang, Shanghai, and Tibet. Since you know China so well, I'd love your advice!
For history, I've read Nanjing used to be the capital of ancient China—should I choose the Confucius Temple or Zhongshan Mountain National Park? In Luoyang, I'm dying to see the Longmen Grottoes. And in Shanghai—I want to see both modern skyscrapers and old alleys! As for Tibet, Mom worries about altitude sickness, but I dream of the Potala Palace. Is that okay for teens?
Please let me know which 1 or 2 cities are must-see, and how to travel between them.
Thanks, cousin! Can't wait to hug everyone and eat Grandma's dumplings together!
Yours,
Alan

Dear Alan,
I’m so excited you’re coming to China! I recommend Nanjing and Shanghai as must-see cities. In Nanjing, Zhongshan Mountain National Park is great for its ancient history, and you can also visit Confucius Temple for tasty local snacks. For Shanghai, you can see modern skyscrapers like the Oriental Pearl Tower and explore old alleys in Tianzifang. You can take high-speed trains between them, which is super convenient. If you want to try Tibet later, just take it slow to avoid altitude sickness. I can’t wait to eat Grandma’s dumplings with you!
Yours,
Lin Tao
