Huangzhong is about 28km southwest of Xining, and although small, it is very important to Tibetans. This is the birthplace of Tsongkhapa (Je Rinpoche), the founder of the Dalai Lama's Gelukpa (Yellow Hat) order, and it is the site of Ta'er Si Monastery, one of the six greatest Gelukpa monasteries. There are many Han and Hui in the town itself but the area around the monastery is full of tourists mingling among the throngs of Tibetan pilgrims who flock to the site from across the Amdo (Eastern Tibet) region.
Bus leaves from Xining Gymnasium (体育馆; Tǐyùguǎn) every half hour throughout the day til evening. The bus takes about one hour to travel to Huangzhong.
To the left and downhill from the entrance to Ta'ersi there is a small area of tourist shops and a scattering a traditional Tibetan restaurants.
Here, you can buy yark acidophilus milk, only ¥2 per bottle, the taste is very good.
The bus station is about 2-3km down the road from the monastery towards Xining. During the day many taxis wait at the entrance to Ta'er Monestary and will leave to Xining only when full. They should not charge much more than ¥50-60 for the trip, so expect to pay about ¥15 per person.
