Additionally, the airport has launched an online advance declaration service in collaboration with airlines. After border inspection staff review and approve tourists' applications, they can obtain a temporary entry permit on-site upon arrival. This enables staff to efficiently deal with an influx of foreign tourists during peak arrival times.

"I look forward to finding opportunities for Chinese investment," said Paulo, a Brazilian tourist visiting Jinan for the first time.
