i’m glad to learn that you are planning to visit shandong with your parents in july. i’m writing to offer some information.
shandong is a great province with a long history and splendid cultures. there are many tourist attractions, such as mountain tai and the former residence of confucius. while travelling, you can experience colorful qilu cultures, learning about many influential philosophers of ancient china. besides, you’d better go to qingdao, which is a beautiful coastal city.
as for transportation, the high speed railway network is the top choice, which will make your journey comfortable and pleasant. if you want to explore a city, shared bikes are worth using.
looking forward to your coming.
