i done researching myself online, for Kuala lumpur , the house price to income ratio per person in kuala lumpur is 25. and the the house price to income ratio per person in china first tier city is 60-70. and 35-45 for 2nd third tier city.  both is checked based on per person income.

china city housing prices is definitely higher compared to malaysia. one of the main reason is that malaysian properties prices are the lowest in south east asia, even when compared to thailand , vietnam, where malaysia gdp per capita is  3 times of vietnam.

but anyhow China first tier city, the housing is definitely not affordable compared to kuala lumpur, and is also one of the highest in the world.
