Alpacas(羊驼) are members of the camel family, having lived in South America for thousands of years. Their fur gives the animals a teddy bear_like appearance. Alpacas are too small to be used as animals of burden but are valued only for their fur. Generally, their lifespan is around 15 to 20 years.

    Alpacas are social animals that live in family groups made up of a male, females and their young. They are gentle, elegant, curious, intelligent and observant. They are safe and pleasant to be around, moving gracefully and slowly around the field, and are therefore unlikely to run into or over anyone, even small children. Occasionally, an alpaca will spit snd kick, but the soft padded(有爪垫的) feet usually do little more than just“get your attention”.

    Because these animals are environmentally friendly and need so little grass and food, you can usually raise from two to eight alpacas on an acre of land with grass or hay. A single, 60 pound bale(大捆) of hay can generally feed a group of about 20 alpacas for one day. Alpacas also require access to plenty of fresh water to drink.

    Alpaca fur is used for making knittedd and woven(编织) items, just as sheep's wool is. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles(针织品) in South America, and sweaters, socks, coats and bedding in other parts of the world. The fur comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia and 16 as classified in the United States.

    How Did the Ancient Chinese Keep Food Warm in Winter?

    Facilities like electric rice cookers, microwaves, and electric kettles, make it easy for people to keep food warm and enjoy a comfortable winter. So how did Chinese people in ancient times keep food warm in winter without these? In fact, ancient Chinese people used their own methods of heat preservation as early as the Shang and Zhou Dynasties.

    ☆ “Wen Ding”, ancient rice cooker

    One of the major functions of an electric rice cooker is to keep food warm. The “Wen Ding”, an ancient cooking container, served the same purpose, but instead of using electric energy, the ancient cooking container preserved heat by burning fuels like charcoal.

    The “Wen Ding” unearthed in Nanjing in 1989 is thought to be the oldest of its kind discovered in China, dating back to the Stone Age. The craftsmanship of making the “Wen Ding” was developed in the Bronze Age. The bronze Ding from the Shang and Zhou Dynasties took on different shapes and structures.

    ☆ “Ran Lu”, ancient small hot pot

    The “Ran Lu” is a small size cooking vessel (器皿) made of bronze, which can be divided into three parts. A charcoal stove forms the main structure, with a bottom tray to hold charcoal ashes, and a movable cup at the top. Some experts have concluded that the vessel's structure suggests it may have been used as a small hot pot and that these vessels became popular in the Warring States Period (475—221 B.C.).

    ☆ Bronze You, ancient kettle

    The Bronze You was one of the most common wine containers during the Shang and Zhou Dynasties. The Bronze You can also be used to warm wine. For example, the Bronze You with beast mask design, unearthed in Jiangxi Province, has an opening where charcoal could be placed. Just as people today can't do without an electric kettle, the Bronze You allowed people to enjoy a hot drink.

    ☆ Bronze Yan, ancient steamer

    Although the “Wen Ding” was effective at keeping food warm, the ancient Chinese people later found that its burning process produced pollution. As a result, the Bronze Yan made with a two-tier structure and used to steam rice and other grains. After the Eastern Han Dynasty (25A.D.-220A.D.), further improvements to the Bronze Yan led to the modern-day steamer.

    Beneath the water in the China's Qiandao Lake lies a hidden treasure. The ancient city of Shi Cheng (also known as Lion City), located in the province of Zhejiang, has been submerged underwater for 53 years. Shi Cheng was founded about 1,300 years ago in a valley surrounded by the Five Lion Mountains. When the Chinese government decided they needed a new hydroelectric power station (水力发电站)， a dam and man-made lake were constructed and the city was left at the bottom of this new body of water. Now, it sits at depths ranging from 85 feet to about 103 feet.

    Much like the Machu Picchu ruins in Peru, this underwater city remained forgotten until some renewed interests lead to its rediscovery. Qiu Feng, a local official in charge of tourism thought about utilizing Shi Cheng for entertainment on the lake and as a destination for diving clubs. On September 18, 2001, scuba divers made their first attempt underwater. "We were lucky. As soon as we dived into the lake, we found the outside wall of the town and even picked up a brick, "Qiu told Guangzhou Daily in an interview. More research was conducted, and it was discovered that the entire town was intact (1881), including wooden beams and stairs. After the initial findings, international archaeologists and a film crew then recorded the preservation of the lost ruins.

    Looking at surface of the lake, dotted with over 1,000 islands, you'd never know that an entire city was below.

    It's incredible to think that after all this time, the structure still remains intact and we could one day visit it. Until then, Shi Cheng will continue to remain inconspicuously submerged.
