Interactive China Map: How Chinese Travelling Home for Lunar New Year


This Friday (31 Jan) is the new year day of Lunar New Year in China, which means it is the beginning of “Chunyun”, a holiday that people travelling home for family gathering. Here is an interactive China map, created by Baidu, for tracking all congestion.

Basically, it is a hell for travelling during this period, and BBC has mentioned that Beijing’s major train stations is know as “the busiest place on the planet” with horrible traffic jams. In order to keep tracking the congestion, Baidu (similar to Google in China) has launched the interactive live map for updating all the trips in each hour. Map users can also search data by date, time, and city. There are also charts list out the most popular cities for arrive at/departure. Currently, Beijing is the main target city that Chinese are travelling to, and Chongqing is the second most popular city. Meanwhile, Beijing is also the most popular city for departure, which is understandable that most of the Chinese work in capital and travel back to home for celebrating festival. So it is not surprisingly that Shanghai places second in the list.

Though this live map provides useful information, but it is only useful to Chinese or those who knows Chinese as the map does not support other languages, e.g. English. Furthermore, the map does not support pan and zooming that users can either search cities in the search box or mouse click the cities in the chart.

Heat Map: Average Scores for PISA tests around the world


Today, the score report of the Programme for International Student Assessment (PISA) tests 15-year-olds around the world on reading, math and science is released that the report is released every three years. Washington Post has then created following heat map for presenting the average scores across the world by countries that countries with bluer colors obtain higher scores.

According to the report, regions with highest scores are Shanghai(China), Singapore, and Hong Kong while the Peru gains the lowest score in this test. The United States ranks 25th with an average score of 1476, which is behind most of Western European countries.

However, according to Washington Post, this report is not really fair as urban areas tend to outperform non-urban areas in education, and developing/poorer countries do not have as much public education programs as developed/richer countries.

interactive-google-map-china-bird-flu-virusThe deadly new strain of bird flu (H7N9) has been found in China, and China has confirmed 16 cases of H7N9 nationwide, with patients ranging in age from 4 to 87. A clickable Google Map has been created to report the latest news of this issue.

The map is created by George Chen,an editor of South China Morning Post, and marks the locations with confirmed H7N9 cases. The red markers show the deaths, the blue markers show the confirmed H7N9 infection, and the pink markers show other strains. Click on the markers, and detailed information about each case will be displayed.

Friday, China has confirmed 6 deaths cases in eastern China, and the Authorities stressed they have yet to find a case of human-to-human transmission and the current cases were appeared to come from human contact with birds.

The world has become more familiar with avian flu over the past decade, for example the spread of H5N1 avian flu, which has proved frighteningly deadly—killing 60% of those it infected, in the past. And the new H7N9 is more worrying than H5N1 due to the genetic changes in the avian virus, which may be adapting to infect mammals.
