The intervention lasted 2 years with involving all participants. Based on the recommendations of the American Heart Association and the China Guidelines for Prevention of CVD [The health education included regularly organizing experts to give health lectures (at least half a year), putting up posters (quarterly), sending text messages, and distributing health education materials to educate employees on the risks of prevention of CVD. A reasonable diet included providing nutrition education and/or healthy eating information (e.g., control the total calories, limit the intake of oil, pay attention to the calorie distribution of three meals, nutrition balance) to employees and opening low-salt dishes windows (open at least one); affordable and healthy foods (e.g., low-salt, low-fat) were easily available, and participants were encouraged to make healthy food choices when eating lunch in the staff canteen, advising families to use as little cooking salt as possible (e.g., use a quantifiable salt spoon, try not to drink soup, reduce the amount of sodium-salt condiments such as glutamate, soy sauce, and so on). In addition, employees were encouraged not to drink alcohol as far as possible. If they do, a small amount of alcohol should be taken: the daily alcohol intake for women is less than 15 g/day, and for men, it is less than 25 g/day, no more than twice a week (15 g alcohol = 300 ml beer/150 ml wine/50 ml low-alcohol liquor). With regard to the smoking cessation section, we included disseminating the concept of smoking cessation, teaching methods and techniques for smoking cessation, distributing information pamphlets on smoking cessation, and establishing tobacco control regulations to increase smoking cessation rates among employees and to prohibit smoking in the workplaces. Improving the physical environment included modifying workstations and office layouts to reduce sedentary behavior and increase physical activity. The physical activity section encouraged participants to increase physical activity and advocated to actively fitness activities, for example, added sports facilities appropriately, encouraged to take elevators less and walk stairs more, organized and advocated various forms of physical activities such as workplace exercises, sports meetings, and regular group sports events (at least 2 items are completed). Accessible indoor or outdoor sports facilities, including indoor walking paths, were provided to allow employees in regular physical activities, encouraging employees to achieve their desired weight goals in a healthy way [body mass index (BMI) < 24 kg/m
