The management fee, including the service fee mainly for property management, maintenance and repair, and security, is recognized quarterly over the terms of the tenancy agreements.   Real estate sales Revenue from the sales of development properties is recognized by the full accrual method when the sale is consummated.

Sales transactions not meeting all the conditions of the full accrual method are accounted for using the deposit method of accounting. Under the deposit method, all costs are capitalized as incurred, and payments received from the buyer are recorded as a deposit liability.   Real estate capitalization and cost allocation Real estate held for development or sale is stated at cost or estimated net realizable value, whichever is lower. Costs include land and land improvements, direct construction costs and development costs, including predevelopment costs, interest on indebtedness, real estate taxes, insurance, construction overhead and indirect project costs. Selling and advertising costs are expensed as incurred. Total estimated costs of multi-unit developments are allocated to individual units based upon specific identification methods.   Impairment If real estate is determined to be impaired, it will be written down to its fair market value. Real estate held for development or sale costs include the cost of land use rights, land development and home construction costs, engineering costs, insurance costs, wages, real estate taxes, and interest related to development and construction. All costs are accumulated by specific projects and allocated to residential and commercial units within the respective projects. The Company leases the land for the residential unit sites under land use rights with various terms from the government of the PRC. The Company evaluates the carrying value for impairment based on the undiscounted future cash flows of the assets. Write-downs of inventory deemed impaired would be recorded as adjustments to the cost basis.

Under this method, deferred income taxes are recognized for the tax consequences in future years of differences between the tax basis of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates applicable to the periods in which the difference are expected to affect taxable income.   The Company records a valuation allowance for deferred tax assets, if any, based on its estimates of its future taxable income as well as its tax planning strategies when it is more likely than not that a portion or all of its deferred tax assets will not be realized.falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18780-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -URI http://asc.fasb.org/subtopic&trid=2144681 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 30 -URI http://asc.fasb.org/subtopic&trid=2144749 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 50 -Paragraph 19 -URI http://asc.fasb.org/extlink&oid=6907707&loc=d3e32840-109319 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 954 -SubTopic 740 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6491622&loc=d3e9504-115650 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 50 -Paragraph 17 -Subparagraph (b) -URI http://asc.fasb.org/extlink&oid=6907707&loc=d3e32809-109319 Reference 7: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 45 -Paragraph 25 -URI http://asc.fasb.org/extlink&oid=21917399&loc=d3e32247-109318 Reference 8: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 740 -SubTopic 10 -Section 45 -Paragraph 28 -URI http://asc.fasb.org/extlink&oid=21917399&loc=d3e32280-109318 false0Income taxes15false 2us-gaap_ConcentrationRiskCreditRiskus-gaap_truenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Financial instruments that potentially subject the Company to concentrations of credit risk are cash and cash equivalents, accounts receivable and other receivables arising from its normal business activities. The Company places its cash and cash equivalents in what it believes to be credit-worthy financial institutions. The Company maintains large sums of cash in two major banks in China. The aggregate balance in such accounts as of June 30, 2013 was $ 6,484,673. There is no insurance securing these deposits in China. The Company has a diversified customer base, most of which are in China.   The Company controls credit risk related to accounts receivable through credit approvals, credit limits and monitoring procedures. The Company routinely assesses the financial strength of its customers and, based upon factors surrounding the credit risk, establishes an allowance, if required, for uncollectible accounts and, as a consequence, believes that its accounts receivable credit risk exposure beyond such allowance is limited.falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for credit risk.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 944 -SubTopic 825 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=28088331&loc=SL29635902-196195 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 20 -URI http://asc.fasb.org/extlink&oid=28364263&loc=d3e13531-108611 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 21 -URI http://asc.fasb.org/extlink&oid=28364263&loc=d3e13537-108611 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 55 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6875567&loc=d3e14489-108613 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 942 -SubTopic 825 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=6480020&loc=d3e61082-112788 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 942 -SubTopic 825 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6480020&loc=d3e61044-112788 false0Concentrations of business and credit risk16false 2GCIH_StatementOfCashFlowsTextBlockGCIH_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00Cash flows from the Company's operations is calculated based upon the local currencies.

This ASU is effective for the Company in the first quarter of fiscal 2014. We do not expect the adoption will have a significant impact on our consolidated financial statements.   In March 2013, the FASB issued guidance on a parent companys accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. This new guidance requires that the parent company releases any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The new guidance will be effective for us beginning July 1, 2014.
