World Preliminary Round of 12 in Asia, the Chinese men's football team challenged japan away, in the 13th minute, Daji Yong also hit a penalty and scored first, so is there any problem with the penalty of this penalty?

This game is Li Xiaopeng's debut in charge of the national football team, he did not use the three-guard formation, but instead played 4231, Zheng Zheng played left-back, Zhu Chenjie played left center-back, and Wang Shen played as left back beyond expectations.
The Japanese team played behind the national football team's left defensive line, using Junya Ito's forward insertion. In the 13th minute, this tactic worked, Jun Ito also crossed from the bottom line, Wang Shen raised his arm when he fell to the ground, the ball hit his arm, and the referee decisively awarded a penalty! The great forced courage also achieved overnight.
Is the penalty award controversial? Let's look at the rules. A handball foul is a case of:
First, deliberately touching the ball with the hand or arm, such as moving the hand or arm in the direction of the ball; second, the hand or arm makes the body unnaturally larger, causing the hand or arm to touch the ball; third, the hand or arm is above/above the height of the shoulder.
Judging from the slow-motion replay, Wang Shenchao's arm was raised, the body range was expanded, blocking the line of the ball, and the height of the arm was obviously higher than the shoulder, so the penalty was awarded, there was no problem, there was no dispute.
