Watch ... the NBA won’t allow them into the stadium with those shirts on.
The majority of the large Chinese community in the Toronto area have their origins in the HK-Guangdong region of China. There has been an influx of Mandarin speaking Chinese in the last 20 years. I have many Mandarin speaking friends and most are happy to be out of China and have no affection for the Chi-com government. There is a significant minority, unfortunately, who have their real allegiance to China, not to mention those who are paid operatives of the Chinese government. The tension between the two groups has the potential to split the Chinese-Canadian community into warring factions.
So where a shirt over the tee shirt.
If the league/venue demands fans lift up their shirts for a tee check, there’s gonna be even more heck to pay...
