Are the road signs in Singapore written in Chinese?

There are no Chinese characters on the road signs in Singapore. Only each platform of the subway station is equipped with Chinese instructions. However, there are many Chinese here, and most of them can speak simple Chinese. It's no problem to ask restaurants and toilets, but if you take out a Chinese road name and ask the other person how to get there, I'm afraid none of them know where the Chinese road name you said is, because there are no Chinese road signs on the road, and they only know what they are familiar with because of the road name.
