How can my son and girlfriend make friends when they travel to Weihai and then to Inner Mongolia?

1. My son and girlfriend have just completed a romantic trip to Weihai and embarked on a magnificent adventure in Inner Mongolia. These two young people are experiencing the beauty of nature and the infinite possibilities of the world.

I feel very gratified to see my son immersed in the joy of traveling. I wish my son a journey full of happiness and good memories.
