Xi gifts Italian president lunar soil collected by Chang'e-5

Chinese President Xi Jinping gifted Italian President Sergio Mattarella lunar soil collected by China's Chang'e-5 lunar probe at the Great Hall of the People in Beijing on Friday.

Xi's gifts to Mattarella consist of an ornament featuring the Chang'e-5's lunar exploration with lunar soil in its moon-shaped section, and research sample scooped and drilled from the moon, which demonstrates the high level of China-Italy cooperation in aerospace.

Mattarella is on a state visit to China scheduled for Nov 7 to 12, at the invitation of Xi.

A company in north China's Inner Mongolia Autonomous Region has adopted a smart management system and cutting-edge technologies to maintain coal transport trains, guaranteeing a steady energy supply during the winter months.

Inside the maintenance workshop of the National Energy Group Railway Equipment Company in Baotou City, large coal transport trains were disassembled into individual parts for careful examination.

Traditionally, at least two workers were required to complete the procedures of disassembly, overhaul, inspection and assembly, and manually transfer heavy components and parts, up to tons, a day. Now, a single robot can do the job more quickly, safely, and efficiently.

The use of intelligent technologies, including ultrasonic testing for detecting defects in train axles, has greatly improved the accuracy and efficiency of inspections. It also offers diagnosis results for follow-up maintenance.

Additionally, smart devices are also incorporated to conduct "X-ray" inspections to check the defects in train components.

To prevent potential accidents, it will be done by both humans and devices for quality guarantee.

"As of December 2, we have conducted maintenance on more than 18,000 trains and 1.01 million carriages annually and solved more than 50,000 faults of various types to ensure stable and orderly energy supply in winter," said Qin Riqiang, a staff member of the company.
