I am emeritus old person, I am in 3 inferior lived 2 years, lived 3 years in the North sea, final decision grows the North sea. I say with personal experience:
1, house price, 3 inferior house price is higher than the North sea multiple, average retiree relies on salary to buy room difficulty, pressure is too great.
2, prices, 3 inferior many price is higher than the North sea, price of green vegetables seafood is high, commodity comes for big land transportation more cost is high, because Hainan is Gu island, when having a typhoon 3 inferior prices soars, not be average person can consume those who rise. And price of price of house of the North sea is not high, suit to live for a long time very much.
3, traffic, hainan is a Gu island, do not have onshore join with the mainland, traffic is very disadvantageous, go Hainan can be mixed by air only boat (the train also is to take a ship) , if have a typhoon,all traffic are interrupted, and the North sea join of one side of 3 annulus sea is terrestrial, provincial capital of big city of airport of the North sea and whole nation almost be open to navigation or air traffic, gao Tie, freeway extend in all directions, suffer a typhoon the impact is little.
4, weather, 3 inferior suit winter only short-term live, summertime temperature is too high, northerner is overcome, I dare not be in 3 inferior over- summer, and Hainan much typhoon. The North sea is inside upper bay, the typhoon is little and small, the summer is not hot, winter is not cold, suit to live for a long time, but the North sea has a month to answer south weather is damp.
5, air, 3 inferior with air of the North sea pretty good, it is oxygen city, hainan is seagirt, the North sea is 3 annulus sea, winter 3 inferior thaw is comfortable, the summer is too hot be overcome, winter of the North sea is in 0 on 10 degrees or so, winter is compared 3 inferior a bit cold but the summer is compared 3 inferior comfortable. Money goes 3 inferior enjoy high price of tall house price, money goes less the North sea. I am seasick, contact 3 inferior can by air, through practical experience, I think the North sea suits average retiree to live more.
