Land-lost farmers here in Chengdu convert to buy social security, why is it two years to count as one year?

No, if there is such a situation, it is illegal. Since they belong to landless peasants, those who have turned from rural areas to non-rural areas can only apply for pension and medical insurance. To participate in social security, you need to apply to the social security bureau where your account is located. According to the actual situation, one year is one year and two years is two years. According to the Social Insurance Law of People's Republic of China (PRC), there is no such thing as two years reaching one year.
