What does the yellow pavement marking at the center of an intersection mean?

[OIsaac]

It's a grid marking. All vehicles are strictly prohibited from stopping either temporarily or for a long time to prevent traffic congestion. Specific explanations are as follows: 1. No stopping: The yellow grid marking on the pavement indicates that all vehicles are strictly prohibited from stopping either temporarily or for a long time to prevent traffic congestion. When there is a vehicle stopped ahead of the yellow grid marking, the following vehicle must wait outside the yellow grid marking until it is confirmed that there is enough space ahead of the yellow grid marking for the vehicle to stop before it can proceed across the yellow grid marking. 2. No occupying: In addition, yellow grid markings are painted in front of important state organs, military units, large enterprises and institutions, and public transport hubs to ensure that vehicles are not blocked by congested vehicles when entering or exiting. The grid marking is yellow, and occupying it when stopping is prohibited.
