Nowadays, it is quite rare to find the Yearly Chinese Alamac or Tung Shu placed above the main door of Chinese homes.
Traditionally, some Chinese would purchase a new Tung Shu (Yearly Chinese Alamac) and place a new copy of it every new year.
It is said that this is to ward off evil and provide good luck.

The Chinese Farmers’ Almanac is still very much alive and well today. Updated every year and usually released around the third quarter, it continues to be a trusted guide in many Chinese households. Commonly known as the Tong Shu (通书), its name can be translated as the “All-knowing Book,” reflecting the wealth of information it contains—from auspicious dates and times to traditional wisdom about daily life. Because of its deep cultural roots, many Chinese people, following the traditions of their ancestors, still place great importance on it—sometimes even treating it as more essential than the Lunar New Year celebrations themselves.

The Tong Shu is produced annually and is often published around the 7th month of the Chinese calendar.
This particular copy is for the Lunar Year 2015.
