Did we achieve the equal pension rights of migrant workers?

In 1999, China entered the so-called "aging society", which has the most elderly population in the world, accounting for the global one-fifth of the total elderly population. The nation's elderly population aged 60 and over has reached 167 million, accounting for 12.5% of the population. The government has estimated, until 2051, the elderly population will reach 437 million the maximum. Needless to say, "old age" poses a challenges for the future Chinese society, while the pension problem of rural population, and that of 2.2 million migrant workers also need to be addressed.
