In order to be late, healthy and fresh vegetables are also quite hard. )
People living in cities, please go to regular farmers' markets to buy food. These farmers' markets are generally strictly managed, and some have pesticide residue detection. Many of them are generally tested before listing, so we should be relatively at ease.
Only those who go to fixed stalls and carefully buy temporary roadside stalls can. This kind of supplier is highly mobile. Once something goes wrong, it is difficult to pursue responsibility and protect rights and cause unnecessary harm to yourself.
Watch carefully when selling vegetables, and don't buy anything with abnormal color or shape. Some vegetables are deformed due to the use of hormone drugs to ripen.
