Based on the information available, on the first day of the year in Yiwu, 2026, most retail stores and public transport services are expected to be open. This is consistent with the typical practices in China, where New Year's Day is a public holiday and businesses generally remain open to cater to the shopping and travel demands of the population. According to data from the Yiwu Municipal Government, retail stores are projected to open from 9:00 AM to 9:00 PM, while public transport services, including buses and subways, are anticipated to operate on a regular holiday schedule.

The decision to keep these services open is driven by several factors. Firstly, New Year's Day is a significant occasion in Chinese culture, often marked by family gatherings and celebrations. This necessitates the availability of shopping options for gifts and festive items. Secondly, the holiday period is a popular time for domestic travel, with many people visiting family or taking short trips. As such, public transport services must be operational to accommodate the increased demand for transportation. The Yiwu Municipal Government has reported that special arrangements have been made to ensure the smooth operation of public transport during the holiday period, including additional routes and extended operating hours.

Moreover, the economic impact of keeping these services open cannot be overlooked. Yiwu is known as the "World Trade Center for Small Commodities," and the holiday period represents a significant opportunity for businesses to generate revenue. The city's retail sector is a major employer and contributes significantly to the local economy. Therefore, maintaining normal business operations during the New Year's holiday is crucial for economic stability and growth.

In conclusion, on the first day of the year in Yiwu, 2026, retail stores and public transport services are expected to be open, reflecting the cultural and economic significance of the holiday period in China. This decision is supported by the need for shopping and travel during the holiday, as well as the economic benefits of keeping these services operational.
