In June 2015, China Jiaoyuan Corporation accepted the assignment of central air-conditioning cleaning for the Chinese Embassy in Tokyo and the Chinese Consulate in Osaka, which was then handed over to one of its subsidiaries Jiaohui Environment for concrete implementation.  With the joint efforts of all departments of the head office, the project team finsihed the work one month early by overcoming difficulties through hard work. The team was highly praised by the embassy and the consulate. In particular, under a tight schedule, the team also maintained and reloaded the air-conditioning system for the Commercial Section of the Embassy by working overtime, finally resolving the problem that has afflicted the Commercial Section for years.
