Is L single entry visa valid if I go to Hongkong or Macau first?

Hi. I will be in Beijing by the third week of May this year. I already have an L single entry visa for this trip. However, I have another trip to Hong Kong two weeks earlier. Will my entry to Hong Kong be counted as an entry to China in itself? What if I decide to have a side trip to Macau? Will my China L single entry visa be void if I enter Hong Kong and Macau two weeks earlier? As Filipinos, we are not required to have a visa for both Hong Kong and Macau; but I'm confused with a later entry to Beijing. Please help. Thank you
