During the 1. epidemic, operators faced challenges. As a commercial enterprise, it will not only face the competition in the market environment, but also be affected by sudden major events such as similar epidemics. From all walks of life, the industries hit hard by this epidemic are concentrated in tourism, catering, transportation, film and television entertainment, trade export and so on. With the change of time, the predicted influence area will become wider, because the economy is a chain.

2. During the epidemic, education faced challenges. During the epidemic, online education and teaching is definitely one of the hot words. The epidemic has changed "cloud teaching" from "minority" to "majority", making most students and parents who have never been exposed to online education before and teachers who have never been "anchors" become "people on the cloud".

3. During the epidemic period, the transportation industry faced challenges: with some cities taking measures such as delaying the resumption of work, closing cities and isolating them, the transportation industry was greatly affected, including the suspension of high-speed rail, railway, aviation and shipping lines, and the decline in passenger flow. With the gradual easing of the epidemic, the transportation industry is expected to gradually restore its capacity in the second quarter of 2020.

4. During the epidemic period, the real estate and construction industry faced challenges: due to the delay in starting work, migrant workers would not return to work in cities, which had a great impact on construction, and some real estate enterprises would also be affected in the short term. With the relief of the epidemic, such as counter-cyclical adjustment and overweight of monetary policy, it may be beneficial to the development of real estate. Property management is not affected, and medium and long-term quality companies may benefit from the optimization of policy environment and the improvement of mutual trust among owners.
