Extraction of Chen Chen's second milk teeth

Same as the first permanent that Chen Chen had the second permanent teeth grew before the milk teeth shakes.   I called the school dentist to examine Chen Chen.   The blur dentist could not find Chen Chen's classroom and called hubby to tell him that she could not find Chen Chen.   Hubby thought Chen Chen was missing and had a shock.   He suggested that the dentist check with the General office when he realised that it's the classroom that the dentist could not find. The following day, Gong Shang General office called me to fetch Chen Chen home around 4+ pm as Chen Chen had high fever at 38.2 degree.   When I reached home and checked on Chen Chen, he told me he had tooth extraction today.   The dentist extracted his milk teeth.
