They were stunned. None had expected he had such a harsh, menacing voice. "Maybe he should go see a shrink," suggested Janet, patting Pingping on the back as she continued to convulse with sobs.

Nan went out the back door to traipse around the shopping center awhile, his mind still whirling. The sun was scorching overhead, and in no time perspiration soaked the back of his T-shirt. The walk calmed him down some, though he still couldn't focus on any thought. Near the entrance to the photo studio toward the east end of the plaza, a mottled gray pigeon that had to be a crossbreed of a pigeon and a dove limped over, walking on the back of its crippled left foot. Its head kept bobbing at a cockeyed angle as it tottered toward Nan, who had often fed it. Nan fished in his pockets but found only a handful of coins, so he stepped aside to avoid obstructing its path. Before the pigeon passed by, it paused to flutter its wings, which suddenly gleamed in the sunlight. If only Nan had had some crumbs or leftovers on him. He liked this lone bird, which was tough, unafraid of people.

When Nan went back to the Gold Wok twenty minutes later, he became himself again, and without a word set about cutting a basket of eggplants, which were all tender and seedless, handpicked by Pingping at the Cherokee farmers' market. For the rest of the day he was very quiet and did everything he was supposed to do.

PINGPING was still angry with Nan for burning the money. For three days she'd avoid rubbing elbows with him at work, and neither would she speak to him. However hard he tried to induce her to talk, she'd compress her lips. At most, she'd give a faint smile if he said something funny or silly.

On Monday morning the truck that delivered groceries came as usual and left two crates of celeries and napa cabbages and a bucket of tofu at the back door to the restaurant. Without telling Nan, who was supposed to move them, Pingping began carrying them in by herself. As she was lifting a crate, suddenly a tearing pain shot through her back and her knees buckled. She fell on the cement doorstep, unable to pick herself up. " Nan, come and help me!" she called out. Two flies, startled, took off from the tofu, whirling around at a high pitch.

Nan rushed out with a towel over his shoulder and saw his wife lying on her side. Her face was contorted while her hand covered the small of her back. "What happened?" he panted, bending over her. "Why didn't you use the hand truck?"

"Oh, I broke my back!"

"Can you move?"

"I can't. My back snapped." On her eyelashes tears glistened.

As Nan tried to help her get up, she gave a loud moan, which frightened him. He left her there and hurried to the parking lot to fetch their van. He wasn't sure if she had really broken her back, but she looked partly paralyzed. He must take her to the hospital immediately. He told Niyan to ask Shubo to come in and help. If her husband was unavailable, she could just close the restaurant for the morning.

Pingping was rushed into a small room in the ER at Gwinnett Hospital. A lanky male nurse said she couldn't have broken her back. "Maybe she slipped a disk, you know," the fellow told Nan.

Then a tall, rugged-faced man stepped in and introduced himself as Dr. Gritz. He looked at the bruise on Pingping's elbow, already bandaged by the nurse, and then began pressing her back here and there. "Does it hurt here?" he kept asking in a soft voice.

The injury was on her spine, just above the small of her back, but to the naked eye there seemed nothing abnormal. The doctor said to Nan, "I'm going to give her an X-ray to see if there's any bone injury."

"Sure. Do whatever is necessary, please."

The X-ray showed everything was normal, so Dr. Gritz decided to use MRI, which could reveal muscle and ligament damage. Following the male nurse pulling the gurney with his mealy hand, Nan pushed Pingping through a long corridor to the scanning lab. In the semidark room, a woman technician and Nan helped Pingping lie on a narrow table. Before sliding her into the tube of a stout MRI scanner, the woman told Pingping, "If it bothers you too much, just raise your leg to let me know." Pingping nodded, then her head disappeared into the tube. The technician began to produce the images of her lower back.

The machine made rumbling noises like a rickety washer while Pingping lay still as if asleep. Nan wondered whether she was hurting. That was unlikely, as she seemed at ease.

The film of the MRI indicated that a disk was protruded, pressuring some ligaments between two vertebrae. Dr. Gritz said this didn't look like a ruptured disk, so it wasn't an emergency case, and all Pingping should do was rest in bed for a few weeks. He prescribed ibuprofen and a steroid and told her not to move around too much until the pain subsided. She could walk a little when she felt up to it, but she mustn't do any hard exercise. Gritz also referred her to Dr. Levin at a clinic in Norcross. "I'm an orthopedic surgeon," he said to Pingping. "A back pain specialist can do more for you."

Though their substandard medical insurance covered a larger part of the cost, the first hospital bill surprised the Wus, altogether more than three hundred dollars. Both Nan and Pingping were unsettled, knowing this was just the beginning. If only they had bought a better policy. Nan took his wife to Dr. Levin two days later and paid another eighty dollars for the visit. From now on she'd have to see Dr. Levin twice a week. If her pain persisted in two months, the specialist said, they should seriously consider a surgery that helped most back pain patients recover fully. Despite the professional assurance, Nan and Pingping didn't believe it necessary for her to undergo an operation, fearing that any mishap might mess up her spine and paralyze her.

Besides that fear, they had no idea how much they'd have to spend for her medical bills, which became a concern because the restaurant hardly made any money these days-most of the profit went to Niyan and Shubo. What's more, Pingping might have to see a physical therapist or chiropractor, according to Dr. Levin. Goodness knew how long those therapeutic sessions would take. Every day Nan wrapped a hot water bottle with a towel and tucked it against Pingping's back. He also gave her massages, manipulating her spine gently in hopes of restoring the slipped disk fully to its original position. She groaned whenever he touched the injured area, yet after each massage she felt slightly better, so she let him work on her twice a day. She was easily depressed, irritated at herself, and often said she was a total nuisance.

"That's all nonsense," Nan would tell her.

He was afraid Pingping might never be normal again; worse still, that she might suffer sciatica even if the injury healed. Dr. Levin had said that Pingping's long working hours had taken a toll on her lumbar muscles, which must have precipitated the disk prolapse. This also meant it might be difficult for the Wus to continue running the restaurant as before. These days Nan had been thinking of looking for a full-time job that provided full health care benefits. If he found such work, he'd sell the restaurant. He talked to his wife about his thought, and she agreed to let go of the Gold Wok, though she wept afterward, hating to part with their business. Yet both of them knew this might be the only sensible thing to do.
