In a trade union customized shuttle bus and a parking spot for new energy vehicles near the management committee of Dalian High-tech Zone, a number of buses and electric vehicles with the words "trade union bus" printed on their bodies are parked. Workers nearby can take the shuttle bus customized by the trade union as long as they take out their mobile phones and operate the "Hydrogen Travel" APP a few times. To the high-tech zone employee apartment composed of several high-rise buildings, there are young employees who have just joined the job and high-level imported talents who live temporarily. Outside the apartment, dozens of smart bicycles with the same color that provide interval travel services for employees are neatly parked in the carport.
