Generally, a Chinese name should sound good and carry an auspicious connotation for it's believed a baby's name is connected with his or her destiny.

Yao Xue and her husband Wang Xiao, in their late 20s, have just experienced some of the difficulties involved in finding a name.

The couple, both graduates of a prestigious university, had a baby girl last October. After the first excitement, giving her a name became a priority for the whole family, including the four grandparents.

Initial discussions, with the six adults offering their own ideas from their own knowledge and using dictionaries, ended without an agreement.

Then Yao recalls once testing her name on a numerology website that said her name was problematic based on the calculating of her bazi, or "eight characters of her birth."

"You have to survive a lot of difficulties to succeed in middle age; you will often quarrel with your husband; you will not be in a good mood in your old age ..." the explanation reads.

According to the "Book of Change," or the "I Ching," which describes the system of cosmology and philosophy that is intrinsic to ancient Chinese cultural beliefs, the eight characters are in four pairs denoting the time, date, month and year of a person's birth.

Each pair is represented by one Heaven Stem and one Earth Branch, ancient measurements of time. And each character has its associated polarity -- yin and yang, and the five elements -- gold, wood, water, fire and earth.

Yao is afraid that someday her daughter would do the same thing as she did -- test her name on a numerology Website. "It would have a bad effect on her if the result was not desirable, " Yao says.

So Yao went to a friend's father, an amateur "I Ching" enthusiast for help. Yao was told her baby lacked "fire" in her bazi. It's normally difficult for a person to have all five elements, but a name can make up for deficiencies.

She took the suggestion of adding "fire" to her daughter's name. Yao and her husband enlarged the naming team to more than 20, including friends and relatives. There was still no agreement.

Professor Wang Daliang, from China Youth University for Political Sciences and an expert on names, says that "increasingly young couples pin more hope on children's names, as they are single-child parents themselves, and their babies are mostly only-children."

Naming a child in fact is a reflection of societal movement. Wang says that many Chinese names took a political tone from the establishment of the People's Republic of China in 1949 to the late 1970s. Typical names include Jianguo (to build the country), Yuanchao (to help the Democratic People's Republic of Korea) and Weidong (to safeguard Mao Zedong).

With China's rapid economic development, these trends are fading. And traditional naming methods have become good business.

More than 20 small naming shops are scattered near the Lama Temple in northern Beijing.

Zhang Helin, 32, called "Master Zhang" by other shop owners, says he was the first to run such a business there.

When Yao entered his shop, he was sitting in a broken sofa reading. Half of the 15-square-meter room he rents is his bedroom and the other half his office.

He wrote the baby's eight characters on a paper square and deduced they showed a lack of "fire," which should be added to the name to give her a good ming (destiny).

The number of strokes in the name characters also followed certain rules, Zhang says. For example, 29, 31 and 32 strokes were good for girl, while 34 was not.

After two hours of scouring self-made lists of characters and a small dictionary, Zhang finally offered four names. But Yao didn't like them.

"They sound or look strange," she says.

"It's difficult to choose a name with the character component of 'fire' for a girl," Zhang argues. "You can discuss the names with your family. If they also dislike them, you can call me or send me a text message and I will re-choose for you for free."

He wanted to charge 200 yuan, but this was cut to 80 after bargaining.

Zhang says competition has become intensive. "It was easy to get a business licence for 'information consulting' around 2003, and businesses sprouted all around the temple."
