A user on Mastodon shared information suggesting that Huawei's chip-to-chip interconnect technology is superior to NVLink 5. The user highlighted Huawei's expertise in SerDes design. Analysts speculate that DeepSeek's V4 model may not outperform Google's models in terms of efficiency. However, it is believed to use Huawei's deep learning chips instead of Nvidia's. This development suggests a potential shift in AI hardware reliance.

Multiple Chinese internet giants have placed orders for Huawei Ascend chips, according to Reuters reports. Analysts suggest this surge in demand may lead to supply shortages.

New automation technology for bridge tower steel reinforcement has increased construction efficiency by 60 percent. The world's first integrated intelligent tower machine was deployed for the Shenzhen-Zhongshan Bridge construction in June 2020.

Shenzhen's import and export trade with Africa reached 31.19 billion yuan in the first quarter of the year. Trade value reached 31.19 billion yuan in Q1, a 47% year-on-year increase. The deficit comes amid a context of high bilateral trade between the two regions. The impact of recent customs duty removals is considered relative because African products sent to China were already subject to low taxation. The deficit comes amid discussions regarding the removal of certain customs duties. Bilateral trade between China and Africa remains high despite the deficit. Chinese ambitions involve continuing exports to Africa to consolidate their position as primary commercial partners. Temperatures in Northwest, North, and Northeast China are expected to fluctuate and decrease over a three-day period starting May 1.

The Shenzhen startup index rose 15.45% in April, marking its largest monthly gain and reaching a ten-year high. Shenzhen city's monthly growth reached 12.09%.

Engineers are working to stabilize a 400-ton bridge tower component for the Shenzhen-Zhongshan Bridge. Current efforts aim to develop standardized modules that can be transported and precisely connected at heights of 100 meters, though this approach lacks industry precedent. This process is in the industry and relies on technological innovation to overcome the limitations of traditional manual construction methods. The project requires breaking down complex, changing three-dimensional structures into standardized modules for transport and assembly. Researcher Cheng Maolin proposed using horizontal sections to split multi-layer structures into single layers that can be unfolded into two assemblable planes. The core challenge involves ensuring the precision of the connection between steel bars is controlled within 3 millimeters.

Cross-border passenger volume on the Guangzhou-Shenzhen-Hong Kong high-speed rail has continued to rise.

Cheng Maolin led a team that successfully developed the world's first intelligent rebar production line in June 2020. The project aims to address the complexity of diverse bridge tower shapes in China, where no two bridges are identical.

Chinese electric vehicle manufacturer BYD presented financial figures yesterday showing its seventh poor quarterly performance in three years. The report comes as Europe maintains its 2035 deadline to phase out fossil fuel vehicles.

Huawei is seeking orders for its Ascent 950 chip to bypass US export controls on Nvidia hardware. DeepSig released the B4 model on April 24, which is optimized for Huawei hardware. Huawei expects to ship approximately 750,000 units of this chip this year.
