A. The Plaintiff, through F, completed the construction of the supply of household units among the instant construction works, around December 2015, and completed the construction of the supply of household units to the general 220 households among the instant construction works in February 2016, and completed the construction of the supply of household units to the general 22 households among the instant construction works around April 2016.

The Plaintiff asserted that, from the warden to the police officer in February 2016, the construction of the General “22 household” was completed, and around April 2016, the construction of the “20 household” to the “22 household” was completed. However, the aforementioned “22 household” appears to be a clerical error of the “22 household” and “20 household” to be a clerical error of the “22 household.”
