The temperature difference between day and night on the plateau is large, and it is hot to death during the day, and the temperature drops all of a sudden at night, Bai Jing goes downstairs with pajamas in the dark, and the room on the left side of the first floor is lit, and Bai Jing walks towards the light. There was a pink post-it note on the door, and Bai Jing lit up her phone to look over.

"Disposable slippers are in the bathroom cabinet, twisting to the left is hot water, shampoo is in the wall cabinet" The words of Danzhilong Feifeng Dance are even more handsome against the backdrop of pink. is still a careful person, Bai Jing couldn't help but blush again when she thought about the scene just now.

After taking a hot bath, Bai Jing lay comfortably in the quilt, picked up her mobile phone and brushed the circle of friends, I don't know when it started, the circle of friends has become a stage to show yourself and market yourself.

Bai Jing rarely posts news, because she is a woman with nothing, no boyfriend, no enviable job, and even her dear father left her a year ago. Father is more of a symbol for Bai Jing, he has not been by her side since she can remember, and the time he accompanies her every year is only a little more than a month. When she was a child, Bai Jing always forgot what her father looked like, so a few days before her father came back, she would take the photo and look at it repeatedly, afraid that she would not recognize her father at the station. But even at such a pitiful time, Bai Jing also loves her father deeply, and counts her father's vacation every year with her fingers, and that month of the year is the best for their family of three. Because there are all kinds of good food, all kinds of fun in that month. It was that beautiful month that became the driving force for all their mothers and daughters' lives, and how hard their lives were made easier because of that month.

I still remember the month before my father left, he was so thin and weak by cancer cells, and his cloudy eyes looked at his daughter by the bed again and again, as if looking at an unknown world through her. Bai Jing was afraid of her father's eyes, as if she was looking at a complete stranger. In the last few days, her father kept holding her hand over and over again, and his mouth was vague, "Go to Gannan, go to the ancient city of Octagon, where there is the tomb of Zao", and in a daze, my father muttered about his Gannan, his ancient city. He served as a soldier in Gannan all his life, and three years later he became a non-commissioned officer in the army, and decades of years were dedicated to the plateau, and even when he died, he missed that place in his heart.

When Bai Jing was thinking about it, there was a low chanting sound from the big room next door, she could be sure that it was the chanting sound, and she had that voice in her dreams since she was a child, with strange turns and tunes, barren and sad. In the dream, there is also a group of monks in red robes, sitting cross-legged in a line, and a woman in a white robe lying motionless on the ground, this dream she lasted for more than ten years, throughout her entire childhood and youth.

Bai Jing was stupefied by this familiar voice, how could there be a dream voice here. Driven by curiosity, Bai Jing got up quietly, looked out the window, and through the moonlight, she could see a few people sitting cross-legged on the kang next door, with a straight posture, and clapping their hands with their hands from time to time, but those people did not wear red robes, they were just wearing ordinary Tibetan clothes, but everyone's hair was very long, and they were all wrapped around their heads, probably three or four times.

What do these people do, and do Buddhists still have hair entanglements? Why this voice appeared in her dreams, countless whys like a worm wrapped around her feet. Bai Jing really wanted to go out and ask what was going on, but because of the identity of her guests, she didn't dare to mess around, and besides, there was a strong religious culture here, so what should I do if I rashly went out and broke the taboo. Bai Jing thought about it and didn't go out, and only fell asleep in a daze when it was almost dawn.

From time to time, there was a sparse sweeping sound in his ears, and Bai Jing slowly opened his eyes. What catches your eye is a solid color of logs, leaning against the corner of the wall, with colorful eight-treasure patterns painted on it. The recessed wall cabinet on the wall is also painted with colorful auspicious clouds.

Bai Jing got dressed and walked outside the house, the gang was gone last night. The large living room was empty. The middle-aged woman last night was sweeping the floor with a broom. Bai Jingpestle was there, not knowing where to go.

"Up? Did you sleep well last night? Leng Buding stretched out a hand from behind his back and patted his back gently. Bai Jing turned around and saw Danzhi with a smile on his face. When I woke up in the morning and saw such a smile full of spring breeze, Bai Jing's mood suddenly seemed to be wrapped in Qiongtian jade syrup.

"Good morning, I slept well last night, but I seemed to hear the sound of chanting in the middle of the night."

"Oh, that's overkill," Dan Zhi habitually scratched his head again.

"Excessive? I don't think they look like monks" After Bai Jing finished speaking, he also regretted it, what is his position for breaking the casserole like this and asking in the end.

"This is a lot to say, we call them "Ogua", which is a sect of Tibetan Buddhism - Nyingma school, they are not like ordinary monks, they are lay people who practice at home, and they can marry wives and have children. ”

"Oh, I see, isn't that a bit too much?" Bai Jing pursed her lips embarrassedly and whispered.

"No," Dan Zhi had a light and breezy look. "Let's eat first, I'm going to the county seat after eating, just a little bit of your way."

"Really, thank you so much, I'm still thinking about how to get to the county seat today?"

"My grandma has already cooked a meal, you wash your face and come to this room to eat," Danzhi said, pointing to a small room on the right.

"Uh-huh, okay"

When Bai Jing finished washing up and came to the room, the meal had already been served on the table. Tsamba ghee, and yogurt. Bai Jing is no stranger, when she was a child, her father would often use it for Bai Jing to eat, saying that it was highly nutritious. So Bai Jing has not only eaten, but is still very familiar with the mixed tsamba. When the ghee was slowly digested in the painted dragon bowl, Bai Jing poured the tsamba on top of the ghee and began to stir, and the familiar action made Danzhi's mother give Bai Jing a thumbs up. He said something he couldn't understand, and his face was full of calm and peaceful smiles.

"My mom said you're amazing,"

"No, my dad used to teach me when I was a kid."

"Did your dad stay in Tibet?" "Well, for decades."

"Oooh".

Along the way, Bai Jing looked thoughtful in the co-pilot, his right hand habitually tapping on the bridge, as if there was a piano underneath, ready to play a song at any time. Danzhi turned his head to look at her from time to time, his eyes full of inquiry.

"I'm going to Octagon City, please put me closest to it."

"I'm fine today, I went to the county seat to refuel, the ancient city of Octagonal is only more than ten kilometers away, I can take you there, there is nothing to see there, it's just an earthen city wall."

"It's too much trouble for you, thank you so much." After Bai Jing finished speaking, she folded her hands together and made a certificate of thanks.

The octagonal ancient city appeared so abruptly in front of Bai Jing's eyes, unlike most of the square city walls in China, the city walls of the octagonal ancient city are cross-shaped. And above the main gate of the ancient city, there is a "swastika" symbol painted with white characters on a gold background. Bai Jing knew that this was the symbol of the ancient Tibetan Bon religion.

In Gannan, this is the only ancient city of Bon, and its inhabitants still practice Bon. He is so alien to the people around him who believe in Tibetan Buddhism, but he stubbornly guards his faith. On the flatlands, hills, and terraces around the Octagonal City, there are layers of terraced fields that were abandoned in ancient times, and in some places the terraces have been cultivated all the way to the top of the mountain. There are about 100 families scattered within the city walls. The houses are all flat-roofed, neatly laid out, and the streets and alleys are crisscrossed. Outside the city, on the terraces of the river valley, patches of yellow rape flowers and green barley complement each other, full of life.

Bai Jing climbed to the top of the north gate wall, and Danzhi followed him at a distance of about one meter. The deep brows and eager footsteps all undoubtedly told Bai Jing's inner excitement. At the end of his life, my father locked himself in the study every day to paint this ancient city, the ancient city of various proportions, and the waste paper thrown into the garbage can again and again declared the bitterness of not finding the answer. Bai Jing didn't know why her father wanted to paint this ancient city, what secrets were hidden in it?

She checked the history, this is a city wall built during the Western Han Dynasty, and during archaeology, she found Han Dynasty tombs and coins from the Wang Mang period. In the Han Dynasty, when the productive forces were not very developed, why did it cost huge manpower and material resources to ram a city out of clay and sand and gravel in this cold and wild land? Is it just because of a military fortress? Bai Jing was thinking hard, what is the magic of an ancient city wall in Saibei that his father will never forget before he dies?

Nothing to the county seat all the way. Bai Jing and Danzhi exchanged mobile phone numbers and WeChat accounts. Bai Jing hurriedly got into the car and went to cooperate, where there was the corps in which her father served, the last cavalry company in China.
