Yvonne Kuegler of Germany loves traveling and sharing.

Last October, her husband was transferred from Germany to work in the Tiexi district of Shenyang, Liaoning province, and she accompanied him with two children.

Over the past year, she has learned a lot about China.

"Seeing is believing," Kuegler said. "The greening in Tiexi district is very good, completely different from the industrial zone. Shenyang is an amazing garden city, a real green city."

She shares such moments with German friends on her personal social media account.

The anniversary of the establishment of China-Germany diplomatic relations fell on Monday. Kuegler hopes the friendship between two countries lasts forever.
