The craft, also known as nuhong, means women39。s needlework and handicrafts, and was popular hundreds of years ago. Photo provided to China Daily International travelers and businessmen applauded Chengdu39。s 72hour visafree policy, which started in September 2021. The policy allows transit passengers, who have a third country visa and valid air ticket, to stay visafree in Chengdu, in Sichuan province, for up to 72 hours. My colleagues and I travel between Chengdu and Vancouver very frequently, so this policy definitely makes our lives a lot easier, said Rudy Buttignol, president and CEO of British Columbia39。s Knowledge Network Co. Buttignol is not the only one who has found the policy convenient. In 2021, a total of million international travelers visited Chengdu, an increase of percent pared with the previous year. Local tourism revenue reached 133 billion yuan ($22 billion) in 2021, an increase of percent from 2021. The policy is also a bonus for the business industry as more businessmen are willing to travel to the city, said Chen Bin, deputy director at the Chengdu Investment Promotion Commission. According to official data, Chengdu attracted billion yuan in investment last year .With 22 Fortune 500 enterprises starting business in the city in 2021, Chengdu is 11 now home to 252 such panies. The policy boosts local tourism and business due to its convenience for foreign travelers, an official said. An Italian architect, was the first person to take advantage of the policy. The CEO of an architectural design firm visited four local panies within three days in Chengdu. After the trip he cooperated with one of the panies to set up his first architectural firm in the city. The new visa policy bees one of our advantages in attracting foreign investment, Chen said. The project manager of the American Chamber of Commerce in Southwest China, said more business delegations would now consider stopping in Chengdu instead of going straight to the traditional destinations such as Beijing and Shanghai.

We n lives in Australia with his family and changed a trip to Japan to visit Chengdu instead after he noticed the new policy. I can e home more often now to meet with my family members and take a walk in those famous scenic sites, Wen said. Chengdu39。s government held a series of activities to promote the policy around the world. In December 2021, Chengdu Tourism Administration, Chengdu Media Group and Chengdu Daily gave 1,000 foreigners a tour of the city. The visitors were from some of the 51 countri es and regions included in the visafree policy, such as the United States, the United Kingdom, Japan, Italy, South Korea, Singapore, France, and Germany. The tourists visited attractions like temples, farms and museums and tasted local foods. Kuan Alley first built in the Qing Dynasty is a popular tourist attraction. Photo provided to China Daily This is such a fantastic experience for me and I know more about the city and its culture now, said Mia, a college student from the United States. Next time when my friends ask me, I will tell them Chengdu has a lot more to explore besides pandas, she added. Chengdu is the fourth mainland city to implement the policy, following Beijing, Shanghai and Guangzhou. An official of the Chengdu Tourism Administration said with more and more international travelers expected to visit in the future, the city is looking to improve tourism facilities and services. Promotion events are part of the marketing strategy and we hope people from other countries and regions realize how beautiful and charming Chengdu is, he said.
