Industrial construction: The construction industry refers to the material production sector of the national economy engaged in the survey, design and construction of building and installation works, as well as in the maintenance activities of existing buildings. According to the National Economic Classification, the construction industry, one of the thirteen sectors of the national economy, consists of the following three broad categories: civil engineering construction; installation of lines, pipes and equipment; and survey and design. The functions of the construction industry are mainly to carry out construction and installation activities for various building materials and components, machinery and equipment, and to build productive and non-productive fixed assets for the national economy. The development of the construction industry is very closely related to the scale of investment in fixed assets, promoting and constraining each other.

Data centres: With the growth of cloud computing on the Internet, the ubiquitous need for 'big data' has led to the rapid growth of the global data centre industry. A data centre is a complex set of facilities. It includes not only the computer systems and other equipment that go with them, such as communication and storage systems, but also redundant data communication connections, environmental control equipment, monitoring equipment and various security devices. In the data centre power supply and distribution system, Liangxin provides professional low-voltage electrical products to ensure the continuous and reliable uninterrupted operation of the data centre.

Commercial and industrial buildings: public buildings are involved in various aspects of people's livelihood, such as culture, sports and education, science and technology, health care and administrative offices. As China's economy continues to grow, people's demand for health, leisure, entertainment and other spiritual aspects will increase, but there is a lag behind developed countries and an uneven distribution. In healthcare, for example, China's per capita medical resources are lower than those of developed countries, and the average urban population has more than 2.5 times as many medical resources as the rural population (the three places with the most resources: Beijing, Shanghai and Tianjin). As a result, the focus of the public construction industry will gradually shift to second and third tier cities in line with the "spillover effect" of first tier cities, thus driving the development of the public construction market in second and third tier cities.

Residential: Residential is the largest component of the real estate industry. At present, the Chinese real estate industry has highlighted the general trend of "consolidation". According to the 2016 annual sales data of the top 100 real estate enterprises, the top 13 real estate enterprises accounted for 50% of the sales of the top 100 real estate enterprises, while there were three real estate enterprises with annual sales of over 300 billion: Evergrande, Vanke and Bi Guiyuan. In the future, the super-large real estate enterprises will move towards the trillion dollar sales club.

Charging facilities: In 2018, the incremental charging infrastructure was 348,000 units, compared to 256,000 units in 2017, an increase of 35.9%, and the incremental new energy vehicle-pile ratio was approximately 3.5:1. By 2020, a "four vertical and four horizontal" intercity electric vehicle fast charging network will be built, with more than 800 new intercity fast charging stations. More than 12,000 centralized charging stations and 4.8 million decentralized charging piles (4 million AC and 800,000 DC) will be added to meet the charging and changing needs of 5 million electric vehicles nationwide, achieving a pile-to-vehicle ratio of approximately 1:1.

Guided rail transportation: China's urban rail transportation shows the development trend of multiple systems synchronization. At present, China's rail transit industry has transformed from a single metro mode to a total of seven systems, including metro, light rail, monorail, urban express rail, maglev, modern tram and APM. It is expected that by 2020, the total length of the planned urban transport network will be more than 6,600km, more than 3,000km more than the "12th Five-Year Plan", and the total investment in construction will reach 2 trillion RMB.
