It was one example of the role that Tianma has played in international coordinated
observations. Its super sensitivity has made its observations useful as a reference by which other parti

“Tianma elevated the image quality of the EAVN, by about 50 percent, making a great co
ntribution to the research on extreme objects in the universe, such as black holes,” Shen said.

Such moves, as well as the increase of tariffs on $200 billion worth of Chinese goods earlier this m
onth, complicated the prospect of continuing the bilateral trade talks that have been ongoing for more than a year.
China has always believed in and hoped to solve trade differences thr
ough talks, but such talks should be equal, Wang said. In any talks, China must protect its legitim

According to the report, most elementary school students were first exposed t
o the internet in third grade, and these 9-year-old students accounted for 32.2 percent of th
e total. For junior high school students, most had their first online experience at the age of 12 years in grade six, a
nd these students comprised 21.7 percent. Among high school students, the peak period to access the internet fell duri
ng their first year in junior high school, with these 13-year-olds representing 19.4 percent.
The report shows over 90 percent of teenagers use electronic devices for study or playing game
s every week. What deserves attention is that the percentage of inevitable exposure to electronic devi
ces among elementary school students is significantly higher than that of the other two groups.
The Central Conservatory of Music will hold a festival from May 23 to 27 to celebrate the 80th anniversary of The Yellow River Cantata.
Written by composer Xian Xinghai (1905–1945) in Yan’an, Shaanxi pro
vince, in early 1939, the piece was inspired by a patriotic poem by Guang Weiran, and the lyrics
were adapted for the cantata. Premiered on April 13 of the same year in Yan’an, the work became, and remains, popular.
The conservatory’s symphony orchestra, choirs and chamber music grou
ps will join in the festival with 20 concerts, including the opening concert on May 23 condu
cted by Yu Feng, president of the university. The Yellow River Cantata will be performed by young singers.
Veteran Chinese musicians and singers, including Guo Shuzhen and Wang Xiufen, will perform during the festival.
Besides concerts, masterclasses and forums will be held in Yan’an.
The music festival will also celebrate the 70th birthday of the country.
oing supply-side structural reform, as it is still dominated by the 268-trillion-yuan banking system, the analysts said.
The restructuring process will accelerate as more foreign capital
moves in, which can boost competition in the domestic market, the analysts added.
In the medium term, continued financial reform and more opening-up measures co
uld boost capital inflows, said Lillian Li, a vice-president at rating agency Moody’s.
But trade disputes between China and the United States and uncertainty over monetary policy in global markets may dam
pen capital inflows, and the pace of capital inflow is likely to fluctuate in the near term, she said.
Having the world’s second-largest equity market and the third-largest bond market, China will likely usher in more inte
rnational capital flows in the longer term, if the nation further liberalizes its financial system, she added.

The two countries should promote the upgrading of bilateral tra

Xi called on the two countries to make joint efforts to celebrate the 50th anni

The draft laws are the latest by Chinese authorities to encourage responsible research practices and increase the effe

Experts said the regulations have been long-awaited in the scienti

Huang Yu, deputy director of the medical genetics department at Peking University, said it used to be difficult to h

With a low mixing layer, Taihang mountain range to the west and the Yanshan mountai

The high level of emissions is the major reason for air pollution in th
e greater Beijing area, and meteorological conditions also play a key role as an exte
rnal factor, said Xu Xiangde, a researcher at the Chinese Academy of Meteorological Sciences.
Zhang Xiaoye, Xu’s colleague, said the “marked effect” of continuous pollutant accu
mulation on meteorological conditions could make overall pollution even worse.
“After the accumulation reaches a certain level, it will further wor

Under a pilot scheme, the first group of six provinces and cities sold 6.8 billion yuan in bonds
at commercial bank counters to individual buyers between March 22 and early April.
The coupon rates are between 3.01 percent and 3.33 percent, higher than treasury b
onds issued by the central government as well as bank deposits with the same maturity.
Gross local bond issuances hit 1.18 trillion yuan in the first qua

The total quota for 2019 local government bond issuances is 3.08 trillion yuan, according to the Ministry of Finance.
“About 60 percent of the bonds were issued for ongoing construction, especially
for shantytown renovation projects, railways and roads,” said Hao Lei, head of the ministry’s Budget Department.
