Is it legal for the property to remove all trash cans?

It is illegal to remove all trash cans from the property.

According to the Law of People's Republic of China (PRC) on the Prevention and Control of Environmental Pollution by Solid Waste, the competent department of environmental sanitation shall, jointly with the relevant departments of the municipal people's government, gradually cancel the paid service charges of environmental sanitation operation service units engaged in garbage transportation and transit according to the requirements of promoting the classification of domestic garbage, and the competent department of environmental sanitation shall, jointly with relevant departments, formulate measures for the management of domestic garbage treatment charges, and gradually implement the differentiated charging policy for classified garbage and mixed garbage.

Therefore, the property can't move all the trash cans at will. If you still have questions about this, it is recommended to consult a professional legal person in order to get a better answer.
