“Lan Caihe’s themes are longevity and nature. Her symbols are flowers and flutes. The Buddhist patroness of florists or anyone who enjoys making things grow, this Goddess often walked the streets playing flute music. Her name means ‘red-footed genius’, alluding to a strong connection with the earth and rich soil.
Around this time of year, people in China drink chrysanthemum wine for longevity and wisdom, eat chrysanthemum petals in salads, and enjoy a plethora of flower displays throughout the land.
If anyone in your neighborhood grows chrysanthemums, definitely try a few petals tossed with a green salad and lemon juice. Consume Lan Caihe’s green thumb and internalize Her awareness of earth directly!
Since it’s September, take a leisurely walk today and enjoy people’s gardening efforts. This honors Lan Caihe and allows you to revel in this Goddess’s artistry firsthand. If you can’t walk around because of bad weather, send yourself a bouquet filled with Lan Caihe’s abundance. When it arrives at work or home, it bears this Goddess’s energy within.
Finally, get out and work with the land in some way today. Plant a little hanging flower arrangement. Weed your lawn or garden. Lan Caihe will reward your efforts with a growing connection to earth and its greenery.”

Wikipedia says that: “Lan Caihe is the least defined of the Eight Immortals (or Ba Xian). Lan Caihe’s age and sex are unknown. Lan is usually depicted in sexually ambiguous clothing, but is often shown as a young boy or girl carrying a bamboo flower basket.
Stories of Lan’s behaviour are often bizarrely eccentric. Some sources dress Lan Caihe in a ragged blue gown, and refer to them as the patron immortal of minstrels. In another tradition, Lan is a female singer whose song lyrics accurately predict future events.
Lan is often described as carrying a pair of bamboo castanets which they would clap and make a beat with by hitting the ground, they would then sing to this beat and a group of onlookers would follow and watch in amazement and entertain themselves. After these performances they would give them lots of money as they asked for it, Lan Cai. They would then string this cash and coins on a long string of money that they carried. As they walked the coins would fall off and Lan Cai. They would not care, other beggars would then take the money.
S/he is often described as wearing only one shoe and other foot being bare, in the Winter it was said S/he slept naked in the snow and it melted and in the summer it was said S/he stuffed His/Her clothes full and wore thick clothes despite the heat.
Like all the other immortals they were often said to be in a drunken stupor and left this world by flying on a heavenly swan or crane into heaven. One day while in a tavern, they had supposedly gotten up to go to the bathroom. But before leaving they flew off on the crane or swan and stripped off their clothes on the way up.”
