Which environmental protection companies in Guangzhou are better?

Personally, if you want to choose them as your customers and let them serve you, you should choose Xindayu. I have been dealing with this company for 1 year and know that their technical content and management are really first-class. If you want to choose to be their supplier, I think you can choose other companies, because they need a large amount of money and take a long time to pay back, unless you are very powerful; If you want to choose to work there, the treatment is definitely environmental protection. My biggest feeling is that the bathroom has air conditioning! Restaurants can be compared with those of bureau-level leading cadres. As for other companies, I haven't dealt with them and I don't know what to say!
