In recent years，the Supreme People’s Court of the PRC has passed a batch of judicial documents concerning public trials，and the local people’s courts have made some progress in adopting various measures to promote the works of open justice，especially in constructing of Three Big Platforms，uploading judgment documents and live streaming of court trials to the Internet. But there are still some problems to be solved. The phenomena of selective openness and pro-forma openness are common. The judicial documents concerning public trials are not fully enforced. The supporting measures have not been taken.
