The Zhu family asked Teacher Chen directly, were the grades announced by Teacher Chen just now really that of Zhu Baoguo, and not Niu Baoguo or other Baoguo. Please don't let it be another person with the same first and last name. They would then be overjoyed for nothing.
They were not young anymore and could not take such jokes, especially now that the Lunar New Year was arriving.
If they showed off the progress of their child to others, and discovered that this was in fact a misunderstanding, that would be so embarrassing.
It was until Teacher Chen's repeated assurance that the grades he announced earlier belonged to Zhu Baoguo, and there was only one Zhu Baoguo in the school, that they knew that this was definitely not a mistake.
Until this very moment, the Zhu family then dared to believe that Zhu Baoguo achieved the groundbreaking results.
