Chinese authorities have intensified flood relief and reconstruction efforts to swiftly restore normalcy in flood-affected regions, following relentless heavy rains that have battered southern China since June 9.

China's National Meteorological Center on Tuesday renewed a red alert for heavy rainfall, the most severe in the country's weather warning system, as the middle and lower reaches of the Yangtze River have been hit by continuous heavy rainfall since June 17.

Forecasts indicate that southern Jiangsu and Anhui, southern Shanghai, northern Zhejiang, central and northern Jiangxi, central Hunan, and western and northern Guangxi in the southern and eastern parts of China will be hit by heavy rains and even extreme downpours from from 08:00 on Tuesday to 08:00 on Wednesday.

Among these areas, southern Anhui, eastern Hunan, central and northern Jiangxi, and western Zhejiang will see particularly heavy rain, with extremely heavy rain forecast in parts of northern Jiangxi. Some regions may also face short-term heavy precipitation, thunderstorms, and gales.

In response, Hunan Province raised its flood control emergency response to level III on Monday.

China has a four-tier flood-control emergency response system, with level I being the most urgent response and a four-tier, color-coded weather warning system, with red representing the most severe warning, followed by orange, yellow and blue.

Northern and central Hunan have been hit by concentrated heavy rainfall starting from last Sunday, with several cities, counties and towns affected by severe rainstorms largely comparable to the "extra-strong" level seen in June-July 2017.

In the next few days, northern and central Hunan will hit by continued heavy rains.

The provincial capital city of Changsha saw 15 waterlogged roads after intense rain on Monday, leading to the suspension of Subway Lines 2 and 3.

After extensive drainage efforts, the floodwater levels at the Changsha Railway Station Square began to recede around 15:00 on Monday.

Despite some train delays, overall transportation at the station is mostly normal. Measures such as anti-slip mats and availability of emergency standby teams have been implemented to ensure passenger safety. In Taoyuan County, Changde City in Hunan Province, heavy rainfall since June 21 has caused flash floods and mudslides, leading to road closures and power outages in Youluxi Village, affecting over 300 villagers.

After a 12-hour search, all villagers were confirmed safe. Restoration efforts have successfully reinstated transportation, electricity supply, and telecommunication in the village.

Local authorities are delivering essential supplies to the affected areas.

In Jing'an County of east China's Jiangxi Province, heavy rainfall on Monday caused a landslide on National Highway 353 in Gaohu Town. Local authorities promptly dispatched personnel to clear the debris, and normal traffic has now resumed.

In the county's Leigongjian Township, rainfall caused partial collapse of a residential compound wall. No casualties were reported, and authorities are clearing debris while advising residents to take alternate routes for safety. Dexing City of Jiangxi Province saw the most significant rainfall of this year's rainy season, leading to multiple landslides and road shoulder collapses.

In response, emergency and transportation departments activated emergency plans, deploying personnel and machinery for rescue efforts.

After intensive work, the affected road sections have been cleared, and some blocked areas are now accessible. Restoration and reconstruction efforts for other damaged facilities are underway.

In Xianning City, Hubei Province, authorities initiated a controlled discharge of water from the Nanchuan Reservoir on Monday morning in anticipation of further heavy rains.

Nanchuan Reservoir, the district's largest, saw the water level on it reach 101.63 meters after heavy rain from June 21 to 23, significantly exceeding its previous level of 97.22 meters. The reservoir successfully intercepted 15.6 million cubic meters of floodwater.

"According to the weather forecast, there will be no significant heavy rainfall in Xianning City from June 24 to June 27. And the water level on the lower reaches of the Gan River has dropped to the normal water level mark, and the Nanchuan reservoir reopened the gate to release water at a flow rate of 50 cubic meters per second," said Zhou Feiyue, director of the Nanchuan Reservoir Management Bureau of Xian 'an District in Xianning City.

By 19:00 on Monday, the reservoir had discharged 1.53 million cubic meters of water, causing a slight decrease in its water level. The controlled discharge is expected to bring the water level down to 99 meters or below.

Persistent rainfall has caused severe flooding in the Songhua River Basin in northeast China, with multiple rivers exceeding the warning water level and four exceeding the guaranteed level. Several large and medium-sized reservoirs are also operating above their flood season limits.

In response to this critical situation, the Songhua River Flood Control Headquarters and the Songliao Water Resources Commission have activated Level IV emergency responses for both flood control and flood prevention.

As significant rainfall is expected to continue over the next week, authorities are closely monitoring reservoir water levels and strengthening flood season water level management to ensure safe passage through the flood season.

China's private manufacturing companies have made significant headway in shifting their conventional business to commercial space industry by stepping up integrated innovation.

As a leading industry player, the No. 2 Construction Machinery Plant of Fangyuan Group, is a long-established private company in Yantai City, east China's Shandong Province, specializing in the production of pile drivers, lifts and other machineries.

This seemingly unrelated company is now thriving as a supplier in the commercial space industry, after upgrading its production lines on the basis of existing large-scale computerized numerical control (CNC) equipment and sophisticated manufacturing technologies.

"We mainly process aluminum materials to a consistent thickness by CNC machining, and then send them to the next factory," said Zhang Wei, production manager of the company.

This factory produces parts that will be used as the bottoms of rocket propellant tank. The products will be sent to another factory 10 kilometers away for the production of propellant tanks.

Private companies did not have the production technology for both the body and bottoms just three years ago, but now, commercial rocket manufacturers can purchase propellant tanks from private companies.

"Our next goal is to shorten the production cycle by half and cut cost by half," said Wang Hailong, deputy director of production planning department of a rocket propellant tank manufacturing company.

According to industry insiders, private companies are estimated to account for over 70 percent in the supply chain system of the commercial space industry with a rising trend in its proportion.

"We are constantly looking for suitable companies in industries such as machinery, aviation, automobiles and consumer electronic and inform them the needs of space companies set up here, while guiding them to continuously upgrade and improve technical capabilities, so that commercial space industry completely opens its supply chain to private companies," said Chu Na, deputy director of the Aerospace Industry Development Center of Haiyang City, a county-level city under the administration of Yantai.

Another private company in Yantai, that originally produce air dome stadiums, has entered the aerospace supply chain through technological innovation. It now produces windproof and rainproof inflatable coat that can ensure safety of rocket during the transport process to an offshore launch site.

In response to the needs of high-performance product and cost reduction, another private company developed a special foam insulation coating used on core components of rockets, by improving and upgrading insulation materials used in the construction industry.

On the basis of innovation on rocket parts production, the commercial space industry is witnessing more and more integrated innovation.

"This is the fourth stage of a rocket. This is the brain of the fourth stage, which used to be four, but now has been [integrated into] one. This is a bracket made of lightweight carbon fiber composite material. Under it, this is a brand-new 3D printed nozzle. We developed these new technologies and new materials together with private companies. Integrating these technologies, we can reduce the cost and production cycle by more than 30 percent," said Gong Yicheng, deputy director of structural technology department of a commercial rocket company.
