As a Chinese native religion, Taoism has a close relationship with Chinese folk customs. With the development of Taoism, it has become deep-rooted in, and the practices of, the ordinary people. This can be seen both in Taoist religious festivals and sacrifice-offerings.

There are many Taoist festivals, and quite a few of them have evolved into folk festivals. For example, the Double Ninth Festival on September 9 of lunar calendar came from the Taoist festival. It is said that in the Eastern Han Dynasty (25-220), there was a Taoist immortal named Fei Changfang, who was resourceful enough to drive all devils away. At that time, he had a pupil called Huan Jing. One day, Fei Changfang foresaw a disaster on September 9 in Huan Jing’s family, and told Huan Jing to fasten a bundle of dogwood onto his arm, and drink chrysanthemum wine in an elevated place so as to prevent the disaster. Having done what he had been told, Huan Jing’s family was indeed safe and sound. Along with the spreading of Taoism, this legend has evolved into the Double Ninth Festival. When the day comes, people will carry dogwood and drink chrysanthemum wine in elevated places.

Many immortals in Taoism came into being on the basis of earthy folk gods, and thus the Taoist god-worshiping system has much in common with the earthy folk god-worshiping. On the one hand, a number of earthy folk gods such as Caishen(mammon), Chenghuangshen(city god), Dongyuedadi(god of East Mountain) and Guanshengdi(god of Saint Guan) have become part of the pedigree of folk gods; on the other hand, Taoist immortals such as Laojun(Holy Lord), Yuhuangdadi(Jade Emperor) and Baxian(eight immortals) have become widespread and part of people’s life.

Moreover, some Taoist taboo tricks have an extensive influence on the folk society, especially in the countryside; or rather, they have constituted a necessary part of folk customs. The combination of Taoism and Chinese folk customs is in various aspects, but it is mainly embodied in celebrations of festivals and seasonal changes and spirit worshiping.

My guide Farah, a tall, slim woman in her late 30s，wears jeans and a simple manteaux -- the required robe women must wear in public, covering neck to knee. Her long, straight black hair is hidden beneath her headscarf, but visible as it curls at her neck.

We’re heading to Tajrish Bazaar, in north Tehran (capital of Iran)，to explore 10 different kinds of dried plums, and other goodies. We choose the Metro—Farah for its convenience, and I，for a chance to go underground in Tehran, because it provides a picture of the city most tourists never see.

It's mid-morning. Women and men sit separately, but the rule relaxes during busy times, like now. We, along with a few other women, clasp our hands around a pole, standing next to men, young and old in the air-conditioned, modern carriage. Two stops later, and about 20 commuters fewer, segregation happens naturally -- women at one end, men at the other, still within view, but separate.

A handful of fashionable girls admire their own reflections in the window. They wear tight leggings under their brightly coloured robes, pushing back headscarves and boundaries. We find seats next to a group of conservative women dressed in black cloaks called chador. They’re nothing like the other women I have met, a sisterhood of outspoken opinions, most of them liberal. “We are a nation with one language,” Farah says, “divided in two—-traditional and modern. ” Farah tells me it all began, not with imports from the West, but with the 1979 revolution. A combination of access, education and a bad economy created a society where women now have independence, careers and husbands happy to help around the house with chores and children*

Birthday card history is said to be over a hundred years old. There is no record to tell us who sent or received the first birthday card but it is said that the tradition of sending birthday cards began in England a century ago. In those times people used to personally greet a person on a birthday, but when a well-wisher was unable to do so he sent a birthday card. Thus birthday cards were more like an apology at that time.

History of greeting cards can be traced back to the ancient Chinese who are said to have started the tradition of sending goodwill messages on New Year Day. Early Egyptians too are believed to have made used papyrus scrolls（纸莎草纸画卷）to send greetings to dear ones. During early 1400 the tradition of exchanging handmade paper greeting cards developed in Europe while Germans at that time were known to have printed New Year's greetings from woodcuts. The advancement in printing technology in 1850s helped to make greeting cards more affordable. No wonder, they soon became popular means of personal communication. During the 1980s non-event cards or the cards not made for any particular occasion became popular and helped card industry reach a new high.

Greeting cards have taken a new form in this present age of Internet technology. Today, they are being increasingly exchanged as electronic or e-greeting cards. Advancement in technology that began in the 1990s has led to a further growth in card industry. People find it easier to send e-cards as a means of exchanging greetings.

Greeting cards are an important means of communicating good wishes and love to a person. They carry a personal touch that makes them lovable and very special.
