Chinese authorities at all levels are making all-out efforts in rescue and relief, as torrential rains continue to wreak havoc, triggering flooding and geological hazards in vast stretches of the country.

The country has entered its rainy season since this month with rainstorms hitting many parts in southern China.

National observatory issued a blue alert for rainstorms on June 29 as heavy downpours are forecast to batter the provinces of Zhejiang, Anhui, Hubei, Jiangxi, Hunan, Guizhou, Yunnan, Sichuan, Hebei, and Shandong from June 29 to June 30, making the regions flood prone.

President Xi Jinping has called for all-out efforts to prevent floods and geological disasters, intensify rescue and relief work, and ensure that people's lives and safety are the top priority.

Xi, also General Secretary of the Communist Party of China Central Committee and Chairman of the Central Military Commission, stressed the need to put people first, and value their lives most in the battle against floods.

He underscored the necessity to coordinate epidemic prevention with flood control and disaster relief work, combine efforts at preparation for prevention with emergency response, strengthen flood monitoring and promptly identify risks.

Meanwhile, in Chongqing Municipality, neighboring Sichuan, more than 210,000 people have been affected by heavy rainfall since June 26.

Chongqing Flood Control and Drought Relief Headquarters deployed more than 50 emergency rescue vehicles and excavators and over 300 speedboats and rubber boats to aid rescuers searching for victims.

Qijiang River that runs through Qijiang District of Chongqing is experiencing the heaviest flooding since 1940.

In Shijiao Township near the river, a group of 30-plus people are on guard observing the flood rise and persuading people to stay away from the river banks.

Zou Hong, Party chief of a community in Shijiao Township, said he has paid door-to-door visits in the community to alert locals of the flooding risk.

In Yuexi County, Anhui Province in  east China, Li Dongliang, a resident in Pinggang Village, is clearing debris left from a mudslide that hit his house over the weekend, when sludge washed down a wall on the ground floor, while he and his family stayed upstairs.

"Local cadres helped us clear piles of silt," said Li.

The disaster relief staff brought excavators, loaders and engineering vehicles to help clean up the silt in their homes, while evacuating those in need to a settlement 3 km away.

Since the start of June, the accumulated rainfall in the county has been more than four times that of the same period in history. Rain-triggered disasters have affected more than 57,000 people. Local authorities have displaced more than 4,400 people to temporary settlements. No one was injured or killed.
