Heatable Brick Beds Warm NE China Homes

In northeast China’s chilly winter, getting into a warm bed is made possible by an ancient heatable brick bed that could date back more than two thousand years     1     is still widely used today. These beds not only bring warmth to local residents, but also continue the folk culture of northeast China.

The bed is made of bricks or other forms of fired clay with     2    width of about1.7 m to 2.3 m and a length that can be determined according to the length of the bedroom. It uses a ducted heating system similar to the Roman hypocaust,     3    (compose) of a stove, a bed and a chimney. The stove     4    (use) to burn firewood. Smoke and heat generated by burning firewood pass through an internal hollow and curved flue system to heat the bed above. Smoke is eventually discharged outward through the chimney. The bed retains heat well,     5    enables people     6    (have) a comfortable sleeping environment in the cold winter. In addition,     7    (sleep) on the heatable brick bed for a prolonged period is good for the blood     8    (circulate) and metabolism of the body, and can relieve some diseases such as arthritis and waist and leg pain.

The heatable brick bed is not only used as a bed, but also a living area for the family. People     9    (routine) have their meals and family     10    (gathering) on the bed in cold winters. The bed is a symbol of home that embodies the emotion and love they feel towards their families.

4 . For thousands of years, Chinese writers have travelled all over the country to take down notes about the geographical conditions of each city. Among them, well-known Chinese geographer and writer Li Daoyuan, in the Northern Wei Dynasty (386-534), composed his book, Commentary on the Water Classics, after studying the original literary version, Water Classics. He later expanded the river records to 1, 252 from the original 137.

The book is now being studied again by Professor Li Xiaojie and his team from Fudan University. They have been using drawing software and 3D modelling to recreate the waterway situations on a map based on the book description. So far, they have completed research on four rivers.

“Ancient people knew really well how to apply the power of nature to technical considerations,”Li said, giving the example of Qianjin’e, one of the most famous ancient water conservation projects in Luoyang, Henan. In order to lead the river into the city for irrigation (灌溉) in ancient Luoyang, the officials built a canal branch by separating a northwest-southeast river. However, the canal water wasn't enough to support the citizens in dry seasons. To solve that, on the northern side of the canal branch, the officials built a reservoir (水库) and a channel to lead the water to the canal branch, where the waterways would converge and flow together to the city.

In Commentary on the Water Classics, a total of 2, 800 cities are recorded with details. Still, the process of recreation takes much effort. After doing a lot of text analysis and fieldwork, the team has gradually created the model with 3D modelling software based on repeated deductions (推论).

For Professor Li, the book is not only a record of the natural landscape over 1, 000 years ago, but also a detailed description of humanity and culture and a treasure for today’s reference.
