>Mars rover completes 100 days on red planet's surface
China's Mars rover Zhurong has spent 100 days exploring the red planet's surface since it first set its wheels on Martian soil on May 22, according to the China National Space Administration on Monday.
The rover is part of China's Tianwen-1 mission that also consists of an orbiter and a lander. The mission was launched on July 23, 2020. As of Monday, Zhurong has traveled 1,064 meters on the surface of Mars, while the orbiter has been in orbit for 403 days. The two are in good condition and functioning properly, according to the CNSA.
The probes will experience a sun outage in mid-to-late September when the Sun is aligned with Earth and Mars, with the solar radiation interfering with the communication between the probes and ground stations. The orbiter and rover will stop working until the sun outage comes to an end, the space administration said.
>China to reduce examination pressure
China's Ministry of Education has issued a circular on strengthening the management of school examinations during compulsory education, in a bid to effectively reduce the pressure faced by students.
No paper-and-pencil exams should be arranged for first and second graders in primary schools, and final examinations should be organized by schools every semester for other grades, according to a ministry press conference on Monday. Midterm exams can be arranged for junior high students in light of the real terms of different disciplines, the ministry said.
It also asked schools to reasonably control the difficulty of examinations and restrict the scope of examinations to their syllabuses and teaching schedules.
Local education authorities should not organize regional or interscholastic exams, and schools and classes should not organize weekly or monthly tests, the notice said.
Moreover, the exam results should be divided into four or five grades, without giving specific scores, the notice added.
The schools should not use test scores to label students or to determine which class to assign them to or where they should sit in class.
Parents and students should be notified of the results in appropriate ways, and the results should not be ranked or published.
>Measures to prevent online gaming addiction
China's National Press and Publication Administration has released a notice on preventing minors from becoming addicted to online games.
Online game providers can only offer one-hour services to minors from 8 pm to 9 pm on Fridays, Saturdays and Sundays, as well as on official holidays, according to the document made public on Monday.
It also urged the strict implementation of real-name registration and logins, saying online game providers must not provide any form of game service to users who fail to register and log in using their real identifications.
Press and publication administrations at all levels have been asked to supervise the implementation of related measures and deal with companies that fail to put measures in place.
In 2020, over 10,000 games were checked by the administration, and more than 50 companies were admonished and handled.
