Worldwide:
The service sector grew fastest after the 1929 crisis. This time is caused by the country's real estate overheating. The general crisis is a period of opportunity brewing for some powerful enterprises. Those companies that are technologically advanced and innovative can rise quickly. For example, after the 97 financial crisis, QQ was born and quickly surpassed MSN, and after the IT bubble in 2001, GOOGLE came into the netizens and brought the world into the new realm of network.
You said after the crisis, I think it is three to five years later. It should be with those Internet technology-related companies such as online games, cell phone linkage, Benben, mutual network companies and other companies focusing on technology service application nature will be very popular
Other catering, clothing, construction and other traditional industries will not grow too fast.
I don't know if you are concerned about China's policy of boosting domestic demand, which focuses on infrastructure. And the results should be visible in three to five years, so it can be said that China's infrastructure, especially applied technology will develop vigorously
