Opened in April 2023, the post office combines traditional postal services with tourism and retail, offering more than 200 local products, from yak jerky and dairy products to highland barley snacks, tea, and matsutake mushrooms. It also sells more than 50 postal souvenirs and offers 10 commemorative stamp designs featuring local attractions.

"I enjoy sending postcards when I travel," said Zou Qianqian, a 23-year-old volunteer with China's Go West program. "Handwriting carries an emotional weight that instant messaging lacks."
