This article studies Starbucks' marketing methods in the Chinese market and how it uses social media to influence consumer choices. The challenges and competition faced by Starbucks after it entered the Chinese market as an overseas brand were introduced. According to the research findings, what Starbucks sells to consumers is not only products but also a high-quality lifestyle. Promoting and localizing products on social media show a trend of current network communication to consumers. At the same time, Starbucks is facing many challenges, such as coronavirus pandemic lockdown, growing competition in China's coffee market, and maintaining its reputation. Doing research and giving corresponding practical suggestions in the face of these challenges are also studied in the article. The development of Starbucks in China is inseparable from the promotion of the Internet and social media, and the loyalty of consumers to Starbucks is also a significant advantage. Starbucks is also striving to develop the resonance between campaign and social practice.

The temperature/pH dual-responsive gel spheres were prepared by orthogonal experiments and response surface methodology, and finally, the optimal synthesis conditions were obtained by a composite score, including swelling, mechanical properties, mass transfer properties, and so forth. The results showed that a sodium alginate concentration of 3% (w/v), CaCl2 concentration of 2% (w/v), gelling time of 40 h, drop height of 14 cm, NaCl concentration of 0.6% (w/v), N-isopropylacrylamide concentration of 0.03% (w/v), and acrylic acid concentration of 4.06% (w/v) were optimal synthesis conditions. The environmental change tolerance experiments showed that the nitrogen removal of the dual-response nitrifying gel spheres was better than the domesticated sludge at low temperatures (4 °C) and in alkaline (pH 9 and 10) conditions. The as-obtained gel spheres can respond intelligently to the changes in ambient temperature and pH. It is hoped that this study will provide technical parameters for the development and application of microbial immobilization carriers.
