The botanical garden also set up a specialized booth where curious visitors like young children can appreciate, touch and even sniff more than 20 types of seed specimens

Chengdu, capital city of southwest China's Sichuan Province, held a splendid science and technology popularization lecture, where seven guests, who are experienced in aeronautics and astronautics, transportation, deep space exploration, and life science, made public speeches to share their insights. Science and technology fans as well as young students across China had the opportunity to attend the lecture both in person and through video links.

In east China's city of Shanghai, residents can enjoy special discounts when visiting 48 science and technology popularization bases. In addition, 56 key laboratories and science facilities will be opened to the public during the science and technology week.

One of the highlights of the week-long activity in Shanghai was a dinosaur fossil unboxing ceremony held in the city's science and technology museum.

Besides showcasing three rarely seen fossils to the public, the museum also offered a grand exhibition where visitors can have the opportunity to appreciate 118 pieces of dinosaur fossils, including 80 Grade I fossils.
