The time difference between Singapore and China

Singapore and China use the same time. Who said there is an hour difference? Don’t talk nonsense!!! I don’t know what the first two heroes thought!!! Where did you hear it!!! Or is it just my own feeling? The time in Singapore and Beijing (commonly used in China) are the same. China Central Television news starts at 7 o'clock, and the local time in Singapore is also 7 o'clock. The Beijing time we say every day is not the time at the longitude of Beijing. I didn't remember it. If it is wrong, the standard time used in our country should be based on a measuring instrument in Shanxi or Shaanxi. Which measuring instrument shall prevail. Of course, it will only be used when very precise timing is required.
