摘要:
On October 25,1971,the 26th Session of the General Assembly of the United Nations adopted Resolution 2758 with an overwhelming majority which restored all rights of the People’s Republic of China in the United Nations(UN)and recognized the representatives of the Government of the People’s Republic of China as the only legitimate representatives of China to the UN.On October 25,2021,Chinese President Xi Jinping attended a conference in Beijing marking the 50th anniversary of the occasion.“The restoration of China’s lawful seat in the United Nations was a momentous event for the world and the United Nations,”he said in his speech.“It marked the return of the Chinese people,or a fourth of the world’s population,to the UN stage.The importance was significant and far-reaching for both China and the wider world.”

摘要:
Wufeng Tujia Autonomous County,Hubei Province,is located in the Wuling mountainous region at an average altitude of over 1,000 meters.Due to multiple ranges of hills,the county was difficult to access and identified as one of nine poverty-stricken regions in Hubei.Fortunately,81 percent of the area is covered by forests and it is also home to 51 wild animals under national key protection.Since 2015,the county has capitalized on its geographic features and formed a leading group to promote industrial breeding of Chinese honeybees.These targeted poverty relief efforts have gradually paid off,and a total of 5,600 households have benefited from raising honeybees on the journey of rural revitalization.
