university. My friend from Mongolian ethnic group was accepted by Beijing University as PhD through Ethnic Minority High-level Backbone Personnel Cultivation Program. During my field research in October this year, I learned a campaign called "I have a home in Xi'an"launched by Chanba No. 1 Middle School in Xi'an city, encouraging local families to give Tibetan kids an adoptive home in Xi'an. Villagers from Hui ethnic group in Hongsipu in Ningxia Hui Autonomous Region relocate from mud hut to cement-built house, securing a stable income in a poverty alleviation plant. The herdsman in Wushen Banner in Nei Mongol said they moved to twostorey houses even ten years ago. Cyber space shall not become a place out of law. Social media shall be employed to convey the truth, but not spread hatred, instigate malicious comments and endanger other countries' security. Thank you .
