Speaking of rape blossoms, I think everyone knows that rape blossoms may be single yellow. In fact, the color of rape flowers is not limited to yellow. Professors of Jiangxi Agricultural University planted 38 kinds of rape flowers, which are not only golden yellow, but also deep pink, deep red, apple red, deep khaki and other colors, which are very ornamental and dazzling. Now that spring has arrived, it is a good season to enjoy flowers in spring. Taking photos in colorful rape fields is also a good enjoyment. Professor of Agricultural University has developed 38 kinds of rape flowers with different colors, which reflects the great progress of China's scientific and technological level.

China is one of the four ancient civilizations, and the only country in the four ancient civilizations whose culture has never been cut off. China has a long history of 5,000 years, and most of the cultures in these 5,000 years are prosperous in China. However, China also had a period of humiliation. Looking at China from the long river of history, the closed-door policy of the Qing government made China more and more backward, and the gap with the developed countries became wider and wider. 1840, Britain opened the door of China with a gun, and then imported a lot of opium from China with real money. Ignorant China people, smoking opium in large quantities, are getting thinner and thinner. Faced with the oppression of foreign powers, the Qing government always bowed its head and begged for mercy, ceded land and paid reparations, and signed one unequal treaty after another, such as treaty of shimonoseki, Xin Chou Treaty and treaty of nanking. These unequal treaties make China go further and further in the dark abyss.

Long-term oppression and pain have made some people in China realize it? Revolution can save the country? Thus, the Republic of China was founded, ending the feudal autocracy in China for more than two thousand years. A weak country without diplomacy will be beaten if it falls behind. This is a lesson that the people of China have summed up in the dark history. After the founding of New China, our country struggled hard under the leadership of the Party, and experienced many hardships from poverty at the beginning to prosperity now. After the reform and opening up, we regard science and technology as the primary productive force and vigorously develop science and technology. China was once overwhelmed by foreign advanced science and technology, but now our country's scientific and technological level has also made great progress, and has made remarkable achievements one after another. We have the world's largest radio telescope Sky Eye, the world's longest sea-crossing bridge, the Hong Kong-Zhuhai-Macao Bridge, and the world's fastest supercomputer Tianhe-2.

Now, China is running on the road of great rejuvenation, and the dragon is taking off. I wish the great motherland prosperity!
