Xi Jinping has warned that investigation and research must not engage in formalism. He said that there can be "prescribed routes" in the investigation, but there should also be "self-selected routes" These flashy investigation methods cannot solve practical problems, but will only make grassroots cadres and masses tired of coping.
Xi Jinping has also put forward four specific requirements, the first of which is "to go deep into the masses sincerely, to make friends with the masses, not to go down to the grassroots level"
