The festival falls on the fifth day of the fifth lunar month (June 7 on the solar calendar 2019). To celebrate the Dragon Boat Festival, people pray for blessings and protection against calamities with vibrant and colorful festivities. The Dragon Boat Festival began to be observed around the Spring and Autumn Period and the Warring States Period more than 2,000 years ago.展开更多

It was first carried to Japan in the 7 th century, gradually developed into Men's Day after more than one thousand years of transformation from routine royal activities and female sacrificial activities, and finally converted into Children's Day today. The Japanese reform of the Chinese Dragon Boat Festival range from the types of celebrations to its meaning with regard to native customs and habits. Although the Japanese government modified and complemented the festival in various historical stages, forming a Dragon Boat Festival with Japanese characteristics, the Japanese Dragon Boat Festival is still heavily loaded with Chinese cultural elements.展开更多

It can move on the rails of a paddy soil bin to simulate the tractive performance of a boat-type tractor in thc paddy field. Kinematics and dynam- ics of the walking device is analysed. Because it can ensure that the blade foot enters and leaves the soil vertically, and eliminates the functions of the soil compression and pick by the blade entirely, so the volume of the blade cavity can be reduced to a minimum and the efficiency of the walking sys- tem has been rasied considerably. Thus, it is feasible to adopt a four-footed walking mechanism in the boat-type tractor.展开更多
