Why do many people in Singapore, Malaysia and other countries speak Mandarin?

There have been several large population migrations in the history of China, the most famous of which was the Eastern Expedition in the early years of the Republic of China. Basically, most people who go to Guangdong mainly come from Shandong.

At that time, Kanto was rich in products. It's like beating roe deer, fishing for fish, and pheasants flying into electric cookers. It is no exaggeration to say that so many Shandong people risked their lives to cross the ocean and take root in the northeast.

Today, more than 80% of the population in Liaojihei and other provinces are descendants of Dongdu. Now, in Singapore, Malaysia and other places, they have also come to Nanyang, leaving behind their descendants, but their current household registration in China is no longer ours, and they cannot be called overseas Chinese. They just have the same face and say the same words as us, but they are foreigners.

I remember that in the previous two Olympic Games, Fish Leong was unanimously criticized by netizens for cheering for Malaysian athletes, because Malaysia's opponent was from China.

However, one of the most important problems has been ignored. Fish Leong is not from China, but from Malaysia. As a Malaysian, there is nothing wrong with cheering for her athletes, except that Fish Leong is exactly the same as ours in China. In fact, I always thought she was just a Taiwan Province province.

Not only in Singapore and Malaysia, but also in many places, including Vietnam, Laos and Cambodia. They even live the same life as we do today. It can also be said that those who broke into Nanyang in the past are now living well, because in Malaysia, these Putonghua-speaking Malaysians are all rich.
